The beauty of Tinkercad is that the code you just wrote will run on a physical Arduino Uno with a TMP36 and a heating resistor with zero modifications. The PID constants you tuned in the safe digital world will translate almost directly to the physical world. tinkercad pid control

Imagine you are driving a car. You want to maintain a speed of 60 mph (the ). Your foot is on the gas pedal (the Output ). The speedometer tells you your current speed (the Process Variable ).
// PID Variables float setpoint = 50.0; // Target temperature (Celsius) float Kp = 8.0; float Ki = 0.4; float Kd = 4.0;
float output = P + I + D;
