Goal: Build and simulate a simple PID-controlled temperature system in Tinkercad (Arduino + heater + temperature sensor) and demonstrate tuning and behavior (P, PI, PID).
Instead of temperature, control the angle of a servo based on a potentiometer. The PID will remove any "jitter" from the servo.

Once you have the basic temperature controller working, try these upgrades:
1. The H-Bridge (L293D) & Motor:
2. The Feedback Sensor (Position):
3. The Target Setpoint (Slider):
Before we write a single line of code, let’s demystify the acronym.
Imagine you are driving a car. You want to maintain a speed of 60 mph (the Setpoint). Your foot is on the gas pedal (the Output). The speedometer tells you your current speed (the Process Variable). Goal: Build and simulate a simple PID-controlled temperature
The error is simple: Error = Setpoint - Current Speed.
The Formula:
Output = (Kp * Error) + (Ki * Integral_Sum) + (Kd * Derivative) Appendix: Full Tinkercad circuit schematic (DC motor +
