Tinkercad is widely known for its easy-to-use 3D design and basic circuit building. But beneath its colorful, block-based interface lies a surprisingly robust electronics simulator that can run real-time Arduino code—including fully functional PID control loops.
#include <LiquidCrystal.h> // Optional for display
// PID Memory float integral = 0; float previousError = 0; unsigned long lastTime = 0;
A standard PID loop calculates an (the difference between what you want and what you have) and applies three corrections:
