Tinkercad Pid Control Extra Quality <DELUXE>

Tinkercad Circuits provides a simplified yet powerful environment for implementing and testing PID (Proportional-Integral-Derivative) control using an Arduino Uno. While the platform is primarily educational, it allows for high-level simulation of real-world control systems like motor speed regulation and temperature stabilization. Core Components for PID in Tinkercad

A temperature control system is a common application of PID control. In this example, we will use Tinkercad to simulate a temperature control system using a PID controller. tinkercad pid control

How to run in Tinkercad

  1. Place components and wire as above.
  2. Paste the sketch into the Arduino code window.
  3. Start simulation. Use Serial Monitor to record time, temperature, and PWM output.
  4. For the “heater” use a lamp or resistor; Tinkercad won't model thermal dynamics realistically, so you can emulate thermal inertia by adding a simple Arduino-based thermal model: read PWM and simulate temperature in software (see next section).

Conclusion

🧪 Step 3: The “Aha!” Experiment

  1. Start simulation – Watch the LED brightness change.
  2. Change the “Setpoint” in code (e.g., 30°C → 40°C).
  3. Observe: Does it overshoot? Oscillate? Take too long?
  4. Tune live:

    The error is simple: Error = Setpoint - Current Speed. Place components and wire as above

    // Proportional term double Pout = Kp * error; Conclusion
