Tinkercad Pid Control 📌 🆓

// Turn the PID on myPID.SetMode(AUTOMATIC); }

If you have ever built a circuit in Tinkercad that needed to maintain a specific temperature, keep a motor at a constant speed, or balance a robot, you quickly ran into a problem: real-world systems drift. A fan slows down under load; a heater overshoots its target. The solution to this problem is a PID controller —and surprisingly, you can build, test, and understand one entirely inside Tinkercad’s free Circuits environment. What is a PID Controller? PID stands for Proportional-Integral-Derivative . It is a control loop algorithm that calculates an "error" value (the difference between a desired setpoint and a measured process variable ) and then applies a correction. tinkercad pid control

// Debug: plot to Serial Plotter Serial.print(setpoint); Serial.print(","); Serial.println(input); // Turn the PID on myPID

// PID tuning parameters (start conservative) double Kp = 30, Ki = 5, Kd = 2; What is a PID Controller

void loop() { // Read temperature from TMP36 (voltage to Celsius) int raw = analogRead(tempPin); float voltage = (raw / 1023.0) * 5.0; input = (voltage - 0.5) * 100.0; // TMP36 formula

// Create PID object PID myPID(&input, &output, &setpoint, Kp, Ki, Kd, DIRECT);

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.
