Tinkercad Pid Control

Tinkercad allows you to write clean C++ code in its built-in text editor. While external libraries like Arduino-PID-Library can be uploaded, writing the PID algorithm from scratch gives you full control and insight into how the math handles the simulation environment.

Below is a simplified code structure for a Tinkercad PID simulation: tinkercad pid control

The Proportional term drives the output based on the current magnitude of the error. If the error is large, the correction is large. Tinkercad allows you to write clean C++ code

One of the most common applications of PID control is temperature control. Here's an example of how to implement temperature control using Tinkercad's PID controller block: If the error is large, the correction is large

Use a second potentiometer (representing the actual speed sensor/encoder) connected to another analog pin (e.g., A1). PWM Control:

Gradually increase Kp in your code and restart the simulation. Look at the Serial Plotter. Keep raising Kp until the Input_PV line begins to oscillate consistently around the Setpoint . Cut that Kp value in half.
