Once you’ve tuned your first virtual PID loop in Tinkercad, moving to a physical Arduino with a real thermistor and relay becomes a matter of copying the exact same code. That is the real power: Try it yourself: log into Tinkercad → Circuits → Create new design → Start coding PID today. // Apply output to heater analogWrite(heaterPin
// Variables double setpoint = 50.0; // Target temperature (Celsius) double input = 0.0; // Actual temperature double output = 0.0; // PWM output (0-255)
// Debug: plot to Serial Plotter Serial.print(setpoint); Serial.print(","); Serial.println(input); // TMP36 formula #include <
// Read setpoint from potentiometer (map to 20°C - 100°C) int potVal = analogRead(setpointPin); setpoint = map(potVal, 0, 1023, 20, 100);
