Tinkercad is not just for blinking LEDs; it is a fully capable platform for learning, designing, and tuning PID control systems. With its intuitive graphical circuit editor, full Arduino code support, and powerful real‑time visualisation tools, it provides an accessible yet surprisingly deep environment for control engineering. Whether you are a student first encountering PID theory or an experienced maker testing a new algorithm, Tinkercad’s PID capabilities can accelerate your learning and prototyping, all from within your web browser. tinkercad pid control
Place a diode across the motor terminals (cathode to 5V, anode to Collector) to protect the circuit from voltage spikes. Writing the PID Control Code
void loop() // Read the temperature sensor float voltage = analogRead(tempSensorPin) * (5.0 / 1023.0); Input = (voltage - 0.5) * 100.0; // Convert voltage to temperature in °C // Create PID object PID myPID(&Input, &Output, &Setpoint,
To see the results, use the (icon in the top‑right corner of the code editor) to watch the RPM approach the target value in real time.

: A motor driver (like the L293D) or a transistor to control the power based on the Arduino's PWM signal. 2. How the PID Logic Works The goal is to calculate an Error (
For a third example, consider a system that uses a DHT11 temperature sensor to control a fan motor, maintaining a user‑defined room temperature. The PID algorithm calculates an optimal fan speed (as a percentage, 0‑100%) based on the temperature error.
