To set up your circuit, connect the longer leg of the LED (the anode) to a digital pin on the Arduino (like pin 13), and the shorter leg (the cathode) to one end of the resistor. Connect the other end of the resistor to the ground (GND) pin on the Arduino. This simple configuration allows you to control the LED using code. Now, let’s dive into the coding part! Open the Arduino IDE and write your first sketch. The code will look something like this:
“`cpp
void setup() {
pinMode(13, OUTPUT); // Set pin 13 as an output
}
void loop() {
digitalWrite(13, HIGH); // Turn the LED on
delay(1000); // Wait for a second
digitalWrite(13, LOW); // Turn the LED off
delay(1000); // Wait for a second
}
“`
This code tells the Arduino to turn the LED on and off every second. The `pinMode` function sets pin 13 as an output, while `digitalWrite` controls whether the pin is sending power to the LED.
