  Thread:Servo Help

  PigPerOne June 28, 2025 — 3:14 PM
  I have a honestly pretty dumb question but for whatever reason I cannot
  figure out how to make this servo work correctly. I have a couple problems.
  The first being that the servo always rotates 90 degrees no matter what
  when the sim is first started. The second being that when I do put a write
  function in the void loop it doesn’t work once  nor loop with the lights.
  Here is the tinkercad, help would be greatly appreciated.

  {11, 10, 9},
  {8, 7, 6},
  {5, 4, 3}

const int SERVO_PIN = 2;

Servo servo;

void setColor(int ledNum, int R, int G, int B) {
  digitalWrite(RGB_PINS[ledNum - 1][0], R);
  digitalWrite(RGB_PINS[ledNum - 1][1], G);
  digitalWrite(RGB_PINS[ledNum - 1][2], B);
}

void setup()  {
  Serial.begin(115200);
  for (int i = 0; i < 3; i++) {
    pinMode(RGB_PINS[0][i], OUTPUT);
    pinMode(RGB_PINS[1][i], OUTPUT);
    pinMode(RGB_PINS[2][i], OUTPUT);
  }
  servo.write(0);
  servo.attach(SERVO_PIN);
}

void loop() {
  servo.write(180);
  setColor(1, 1, 0, 0);
  delay(500);
  setColor(2, 0, 1, 0);
  delay(500);
  setColor(3, 0, 0, 1);
  delay(500);
