Reflow Oven Profile Plotter Utility is a freeware application to graph temperature vs time data sent typically from a homemade reflow oven controller eg: Arduino based via serial port to a PC or notebook running Windows 7. The graph generated has two vertical axis for temperature real-time oven temp and setpoint temperature in degrees C.
Horizontal axis is time seconds. Graphed data can be saved to disk and retrieved if needed for reference. The graph can be saved as bitmap file The Reflow Plotter utility was written to operate in conjunction with this controller. This software is to be used as a communication interface for photographic densitometers to receive transmission or reflective density through the serial port RS A graph of the received data is also done automatically.

Debugging sensors on a microprocessor can be a hassle and the most used approach is to output the sensor values to a serial monitor.
I made a realtime plotting tool which is a better and more visual way of doing the same thing. I created this software to debug an Arduino Due on my self-balancing robot. To tune the controls of the robot I needed fast feedback to know if I was making progress or not. The video below demonstrates typical use of the realtime plotter:. The realtime plotter can be expanded to also send commands to the microprocessor.
The usual approach when programming microprocessors is to set some parameters in the beginning of the code, upload them to the processor, see the result, change the parameters again, upload, and so on until satisfactory performance is achieved. This iterative process takes a lot of time and a better approach is to send updated parameters to the microprocessor from your computer via serial data. For example I needed to tune some parameters on my robot and created a command panel that runs in parallell with the realtime plotter.
For each change in parameters I immediately am able to see the result on the plotting screen. I decided to send and receive the data as ascii characters instead of binaries. The greatest disadvantage is performance and ease of use is the main advantage.
In some sense the realtime data plotter can also be used as a very slow and limited digital oscilloscope. I would not recommend using it for any high frequency applications though.
I have tried many different ways of doing this. My first approach was Matlab but I had problems with it locking the serial port. It was a hassle to get it working and getting everything configured takes to much time. My second approach was Python and graphing libraries but this was still not very satisfactory. The Processing language together with a graph library and ControlP5 made the whole thing much easier.Not a member? You should Sign Up. Already have an account?Easy Arduino Data Logging and Telemetry

This release brings some performance improvements, minor features and bug fixes. Instead of "number of samples" option in the "Plot" tab, now there are 2 options you can set.
To see previous samples you simply use the X axis scrollbar. The main reason for this distinction is the performance. Previously you couldn't set number of samples too high because SerialPlot tried to plot all data at one time. Now you can set "Buffer Size" to 1. Another advantage is that, sometimes when you have frequently changing data, zooming way out doesn't mean much, you have too keep a certain zoom level in X axis to be able to see any detail.
If you enjoy the old behaviour you can always set buffer size option same number as plot width and it should be fine. Remember though "plot width" option has a smaller limit then "buffer size" for performance reasons.
A note; performance improvements are not done. I'm still working on some improvements to increase "buffer size" limitations. Also we now have an update checker. You can launch it from the "Help" menu. It will check updates once a day when you first launch SerialPlot unless you disable it.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

That's a useful feature of a plotter. Perhaps it could have an autoscroll button like the serial monitor does. Also, there's no way to capture the serial data when the plotter's open. This is a feature that's been very useful from the serial monitor for years.
As a fix, I suggest a adding a button that has the same functionality as autoscroll in the serial monitor b adding the ability to copy the serial output from the plotter, same as in the serial monitor. This is due to the serial connection object being a part of the serial monitor instance.
This pattern was kept in place for the serial plotter. However, only one connection can be opened per port. To have both the plotter and the monitor open, the serial connection would need to be managed elsewhere.
This could be a SerialConnection singleton, or some other mechanism. Both plotter and monitor could then subscribe to serial events. As that is a bigger refactoring, I didn't touch this when writing the serial plotter. Fair enough. It just makes the plotter less useful than it may seem at first appearance. Any idea how hard it would be to refactor SerielPlotter to be a text monitor as SerielMonitor?
Purpose would be to have a text pane hideable that would show the raw serial output. Sounds nice, but if this is being done it makes no sense to keep the old Serial Monitor. Just have a single tool that combines Serial Monitor and Serial Plotter, with tabs or buttons to switch between "text view" and "plot view". Skip to content.

A basic understanding of electronics and programming is expected along with some familiarity with the Arduino platform. The resources created for this tutorial are available on GitHub for your reference.
I had previously seen it in the Tools pulldown of the main menu, but had assumed that since I did not have a physical plotter, it did not apply to me. I only realized recently that it is actually used for plotting values on a graph and can be a valuable tool for visualizing data along with debugging code. You know what they say about assumptions. If you are using a different Arduino board or computer setup, the vast majority of this tutorial should still apply, however, some minor changes may be necessary.
I am using the Uno WiFi R2 in this tutorial to take advantage of the on-board inertial measurement unit IMU so that I do not have to connect additional hardware.
If you need assistance with your particular setup, post a question in the comments section below and I, or someone else, can try to help you. The code should be fairly straightforward, but if there is something that needs further explanation, please let me know in the comment section and I will try to answer your question.
This is where the generated waveforms will be displayed. If we take a look at the sketch, we see that the plotSineWave function is being called from within the loop function.
Display one of the other waveforms by commenting out the plotSineWave function, uncommenting one of the other waveforms, and rerunning your sketch.
Note, if you see data left over from the previous plot, you will need to close and re-open the Serial Plotter window to clear the screen. Reviewing the plotSineWave function, we see the data is simply being sent using the Serial. As long as only numbers and whitespace are sent over the serial port in a particular format, the Serial Plotter can interpret that data to graph it visually.
This format requires that a new line character be sent in between x-axis tick marks and that y-axis values are separated by whitespace such as a space or tab. Notice that only the last statement, printlnactually sends a new line. You can add more variables as long as you add the appropriate whitespace in between the print statements for each of the variables. Whereas all other wave functions display only a single variable plot, the plotCombinedWaves function displays three different waveforms simultaneously.
View this function for a better understanding of how to plot a multivariable graph.
SimPlot free - 4 channel plotting. Disadvantages: A bit complex to learn but I figured out how to get started in a few minutes, and quite functional in an hour or tworuns in a terminal window if you consider that a disadvantage. Something I found very useful was to script it to reload my terminal program's logfile periodically so i got a dynamic graph as my experiment progressed.
SerialPlot - Realtime Plotting Software
It's not arduino specific in any way, but it is a very excellent Python plotting toolkit. I've built a number of applications that plot data from a variety of microcontrollers in real-time to a graph, but that was really more of a two-step process: 1. Get data from device into computer, 2. SerialPlot free. It does everything you require and much more. For an int data type that would look as follows:.
You can try serialchart. It's pretty strait forward program. It does exactly what you asked. The only disadvantage is that it requires data in CSV format does not meet first point. You might be interested in Telemetry See on Github. If you don't want to read this long post, see A walkthrough of all the awesome features in it. The power of this library comes from the desktop command line interface that requires no programming skills in python. It is able to open high-performance plots much higher that what can be done with matplotlib just by typing a command.
The protocol supports complexes data structures. For now arrays and sparse arrays can be send from the embedded board. The plots opened from the command line interface understand the type of data, and for arrays, rather than plotting each sample versus time, sample will be plotted against its own index. In a near future, it is planned to add support for spatial coordinates xyz datathat will allow you to plot immediately spatial data. Once, again the plots will figure everything out, plot your data in 2D or 3D space and you can focus on developping your app.
Then you can connectls list received topics, print data received on a topic, pub publish on a topic, or open a plot on a topic to display received data in real-time.Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. Both work well, the 8beeing a quarter of the size of the In inches.
So in a NEMA 8 motor, the mounting holes are placed on an 0,8"x0,8" square. Pretty tiny. You can take virtually any servo available.
Pens see dedicated steps It sucks pens dry like nothing, so ballpens are the most efficient, copics the most expensive. There isnt any special thing to consider, just plug the shield to the arduino and give it the code : On thing i found out is, the L drivers get really really hot, so if they didnt came with heatsinks, better add some, or mount a fan like i did. To mount the cooling fan i took a sheet of 3mm fibreglass and cut it with a jigsaw. The fan is pretty strong and loud, i probably add a pot in the future to tune it down a bit.
Basically there are three systems. Beginning with the worst possible version: A spindle and some rope. The problem is, that with spooling of the rope, the spindle-diameter changes, so the calculation isnt correct anymore, which ends in wacky drawings.
A Pearlchain from window-shutters. Very light and precise setup. I have built a big plotter for shop windows and liquid chalk that uses two 3m ropes. The problem with the rope and the pearls is, that it needs special idler pulleys if you wanna use idler pulleys at all.
A belt from 3d printing spares To me the best and most affordable version is a 5mm belt. Its super precise, though i think it flexes more then the rope. The easiest and cleanest version is to just mount a teeth pulley on the motor and let it go. Be sure to add some counterweight, to prevent slip.
If you want or need to make it more complex, i added some photos, that solve different problems i had at that time. On the NEMA17 stepper photos: One thing i always tried to do was to keep distance between the left and right idler pulley as wide as possible.
In a polar v plotter, one situation that is sub-optimal is, when one of the belts hangs down vertically. Thats the position where the motors have the least control about what the pen is doing. I tried to avoid that, by mounting the last idler pulleys wider then the canvas. Next i had to mount a second idler to get the counterweight out of the line.
On the NEMA 8 photo: This will be a small A3 version, that hangs on the wall, framed, and takes portrait of random people. O the goal was to make it as flat as possible. As you can see there is one 90degree twist in the belt to get the motor parallel to the wall. All idlers have double ball bearings and run supersmooth.
There are endless versions how to mount a pen and lift a pen hanging on two ropes. The blue penholder on the photos is made from a segafredo coffeecan some makeblock parts and a servo.
The second yellow version is made for endless-lines drawings without lifting and is made of three ballbearings and three 3mm fibreglass parts. Liquid chalk seems to be some sort of chemical substance that you can paint on windows with and easily wipe it of to clean the windows. Its filled in a regular boardmarker sized pen.
