/*
 Stepper Motor Control - one revolution

 This program drives a unipolar or bipolar stepper motor.
 The motor is attached to digital pins 8 - 11 of the Arduino.

 The motor should revolve one revolution in one direction, then
 one revolution in the other direction.

create arduino code for capacitive touch pad on the pcb connected to d6 in xiao rp2040. when i touch the touchpad i need the servo motor to do one turn. servo motor is connected to d0 as control pin, then power and ground

    #include <Servo.h>

// Pin Definitions
const int TOUCH_PIN = D6; // Connected to your PCB pad
const int SERVO_PIN = D0; // Servo control pin

Servo myServo;

// Threshold for touch detection (adjust based on PCB sensitivity)
const int TOUCH_THRESHOLD = 20000; 

void setup() {
  Serial.begin(115200);
  myServo.attach(SERVO_PIN);
  
  // Initialize servo at 0 degrees
  myServo.write(0);
  
  pinMode(TOUCH_PIN, INPUT);
  Serial.println("System Initialized. Touch the ARDRA pad!");
}

void loop() {
  long touchValue = readCapacitivePin(TOUCH_PIN);

  // If the sensor value exceeds our threshold, trigger the servo
  if (touchValue < TOUCH_THRESHOLD) {
    Serial.print("Touch Detected! Value: ");
    Serial.println(touchValue);
    
    // Perform "one turn" 
    // Note: Standard servos move 0-180. 
    // If it's a 360 continuous servo, this dictates speed/time.
    // Assuming standard 180-degree servo:
    myServo.write(180); 
    delay(1000);        
    myServo.write(0);   
    delay(500);         // Debounce delay
  }
  
  delay(10);
}

// Simple capacitive sensing function for RP2040
long readCapacitivePin(int pinToMeasure) {
  long total = 0;
  for (int i = 0; i < 10; i++) {
    pinMode(pinToMeasure, OUTPUT);
    digitalWrite(pinToMeasure, LOW);
    delayMicroseconds(10);
    
    pinMode(pinToMeasure, INPUT);
    long cycles = 0;
    while (digitalRead(pinToMeasure) == LOW && cycles < 2000) {
      cycles++;
    }
    total += cycles;
  }
  return total;
