Introduction
An essential ability in the world of electronics and do-it-yourself projects is LED interfacing with Arduino or Arduino with LED. Light Emitting Diodes, or LEDs, are adaptable and low-power electronic components that release light when electricity passes through them. Because it offers an easy-to-use method of controlling LEDs, Arduino, a well-known open-source microcontroller platform, is a preferred option for enthusiasts, hobbyists, and even professionals.
What is Arduino?
The open-source electronics platform Arduino is built on user-friendly hardware and software. It is composed of a development environment that enables you to write and upload code to the microcontroller and a microcontroller, which is effectively a little computer. Due to its ease of use and adaptability, Arduino is well-liked by both novice and seasoned electronics enthusiasts.
LED interfacing with Arduino
Basic Components
- Arduino Board
- LED
- Resistors ( 100 ohm )
- Jumper Wires
- Breadboard
- USB cable for code uploading
Circuit Diagram
- Attached the LED on the breadboard
- Connect LED’s positive terminal with Arduino’s PIN 13 through a 100 ohm resistor.
- Then connect LED’s negative terminal with Arduino’s ground pin.
- Connect the USB cable with the Arduino and to the PC.
- After connection upload the code.
Code of Arduino with LED
void setup() {
pinMode(13, 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
}Uploading and Testing
After writing your code, you’ll need to upload it to the Arduino. Connect the Arduino to your computer via USB and use the Arduino IDE to upload the code. Once uploaded, the LED should start blinking.
