Tinkercad Pid - Control

Open Tinkercad right now. Create a new circuit. Drag an Arduino and a DC motor. Write a simple P controller. Watch it oscillate. Then add D to calm it. Then add I to zero the error. You will never forget how a PID feels once you have tuned it—even in a browser.

// Constrain output to -255 to 255 (PWM range) if (outputRaw > 255) outputRaw = 255; if (outputRaw < -255) outputRaw = -255; tinkercad pid control

void motorDrive(double cmd) { if (cmd >= 0) { digitalWrite(dirPin, HIGH); // Forward analogWrite(pwmPin, cmd); } else { digitalWrite(dirPin, LOW); // Reverse analogWrite(pwmPin, -cmd); } } Open Tinkercad right now

// Integral term with anti-windup (clamp) integral += error * dt; double Iout = Ki * integral; 255) outputRaw = 255
