Connect Phase A and Phase B to Arduino Interrupt pins (D2 and D3) to accurately count rotations. Setpoint: Connect the potentiometer center pin to A0 . 💻 Sample Arduino PID Code float Kp = 1

and a heating element (simulated with a resistor or LED). The PID loop manages the heat output to reach and hold a specific temperature. Servo Position Tuning servo motor

The motor is stuck at a limit (e.g., full PWM) but the error persists. The integral term grows huge. When the error changes sign, the integral keeps the output saturated, causing massive overshoot.

To simulate PID, we need a system that can move and a way to measure that movement. A popular choice in Tinkercad is using an to control a DC Motor with an Encoder (or a simple Potentiometer to simulate a sensor).
