Tinkercad Pid Control

// PID Control Simulation Code for Tinkercad // Pin Definitions const int setpointPin = A0; // Potentiometer input const int feedbackPin = A1; // Measured system state const int outputPin = 3; // PWM output pin // PID Tuning Parameters double Kp = 2.5; // Proportional Gain double Ki = 1.0; // Integral Gain double Kd = 0.1; // Derivative Gain // PID Variables double setpoint = 0; double input = 0; double output = 0; double error = 0; double lastError = 0; double integral = 0; double derivative = 0; // Timing Variables unsigned long lastTime = 0; const double sampleTime = 0.05; // 50 milliseconds sample rate void setup() pinMode(outputPin, OUTPUT); Serial.begin(9600); lastTime = millis(); void loop() unsigned long now = millis(); double timeChange = (double)(now - lastTime) / 1000.0; // Convert to seconds // Execute PID calculations at regular intervals if (timeChange >= sampleTime) // Read Setpoint (0-1023) and scale to 0-255 setpoint = analogRead(setpointPin) / 4.0; // Read Current System State (0-1023) and scale to 0-255 input = analogRead(feedbackPin) / 4.0; // Calculate Error error = setpoint - input; // Calculate Integral component with windup protection integral += error * timeChange; if (integral > 255) integral = 255; if (integral < -255) integral = -255; // Calculate Derivative component derivative = (error - lastError) / timeChange; // Compute PID Output output = (Kp * error) + (Ki * integral) + (Kd * derivative); // Constrain output to valid PWM range (0-255) if (output > 255) output = 255; if (output < 0) output = 0; // Write PWM to the circuit analogWrite(outputPin, (int)output); // Debugging out to Serial Plotter Serial.print("Setpoint:"); Serial.print(setpoint); Serial.print(","); Serial.print("Input:"); Serial.print(input); Serial.print(","); Serial.print("Output:"); Serial.println(output); // Save state for next iteration lastError = error; lastTime = now; Use code with caution. 4. Visualizing PID Behavior in Tinkercad

// Pin definitions for motor driver and sensor const int enA = 9; // PWM pin for speed control const int in1 = 7; // Motor direction pin 1 const int in2 = 8; // Motor direction pin 2 const int sensorPin = A0; // Speed feedback sensor (simulated/encoder) const int setpointPin = A1; // Potentiometer for target speed tinkercad pid control

In the Tinkercad Code editor, switch to "Text" mode. The following is a basic structure for a PID controller implementing a PWM output to control an LED's brightness based on the difference between two potentiometers (Setpoint vs. Actual). // PID Control Simulation Code for Tinkercad //
