Tinkercad Pid: Control

// PID tuning parameters (start conservative) double Kp = 30, Ki = 5, Kd = 2;

#include <PID_v1.h> // Define pins const int tempPin = A0; const int setpointPin = A1; const int heaterPin = 9; tinkercad pid control

// Compute PID myPID.Compute();

// Read setpoint from potentiometer (map to 20°C - 100°C) int potVal = analogRead(setpointPin); setpoint = map(potVal, 0, 1023, 20, 100); // PID tuning parameters (start conservative) double Kp

// Create PID object PID myPID(&input, &output, &setpoint, Kp, Ki, Kd, DIRECT); What is a PID Controller

If you have ever built a circuit in Tinkercad that needed to maintain a specific temperature, keep a motor at a constant speed, or balance a robot, you quickly ran into a problem: real-world systems drift. A fan slows down under load; a heater overshoots its target. The solution to this problem is a PID controller —and surprisingly, you can build, test, and understand one entirely inside Tinkercad’s free Circuits environment. What is a PID Controller? PID stands for Proportional-Integral-Derivative . It is a control loop algorithm that calculates an "error" value (the difference between a desired setpoint and a measured process variable ) and then applies a correction.
