// Read feedback position (0 to 1023 from "coupled" pot) input = analogRead(A1);

Clamp the integral accumulation. Or, implement "conditional integration" (only integrate when the output is not saturated). 2. Derivative Noise Problem: In Tinkercad, pots are "perfect" sensors with no noise. On real hardware, derivative term amplifies noise. Simulate this by adding a small random noise to your feedback reading: input = analogRead(A1) + random(-5,5); . Watch the motor jitter.
// Timing unsigned long lastTime = 0; double dt = 0.1; // seconds // Read feedback position (0 to 1023 from
// Proportional term double Pout = Kp * error;
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.

// Time delta for derivative and integral unsigned long now = millis(); double deltaTime = (now - lastTime) / 1000.0; if (deltaTime > 0.05) { // Run PID every 50ms output = computePID(setpoint, input, deltaTime); motorDrive(output); lastTime = now;
