void setup() pinMode(13, OUTPUT); // Set pin 13 as output

Components: 10kΩ potentiometer. Connect middle pin to A0, outer pins to 5V and GND.

void loop() Serial.print("Value: "); Serial.println(analogRead(A0)); delay(500); arduino uno programacion ejemplos

Components: LED, 220Ω resistor. Connect to pin 9 (PWM-capable).

void loop() for (pos = 0; pos <= 180; pos++) myservo.write(pos); delay(15); void setup() pinMode(13, OUTPUT); // Set pin 13

Components: Servo motor (e.g., SG90). Connect signal wire to pin 9, power to 5V, ground to GND.

Components: Push button, 10kΩ pull-down resistor. Connect button between pin 7 and 5V; pull-down resistor between pin 7 and GND. void setup() pinMode(13

int ledPin = 9; int brightness = 0; int fadeAmount = 5; void setup() pinMode(ledPin, OUTPUT);

if (currentMillis - previousMillis >= interval) previousMillis = currentMillis; ledState = !ledState; digitalWrite(ledPin, ledState);
