![]() ![]() * * * This example code is in the public domain. * * MotorKnob * * A stepper motor follows the turns of a potentiometer * (or other sensor) on analog input 0. Unfortunately, there is no user manual for it. The Serial Plotter built into the Arduino IDE creates graphs from numerical data. ![]() ![]() Copy and paste the code below into the Arduino Editor. We are going to first need to modify the code for CIRC08. This is super useful for visualizing data, troubleshooting your code, and visualizing your variables as waveforms. It can give you visualizations of variables in real-time. Using this code, all you have to do is rotate the joystick 45 degrees counter-clockwise and you have an intuitive controller with an inverted vertical axis. How-to Use Arduino's Serial Plotter Elektor Magazine The Serial Plotter built into the Arduino IDE creates graphs from numerical data. Arduino comes with a cool tool called the Serial Plotter. You could make this code as complex as you want, but since this is the SIMPLEST plotter, that's what you get. ![]()
