If you appreciate our work don't forget to share this post and leave your opinion in the comment box. So grab your Arduino and LED, and let your creativity shine! With this guide, you can confidently take on the challenge of interfacing LED with Arduino and start experimenting with more complex hardware projects. By understanding the concepts of LED, its pinout, connection with Arduino, and the code involved, you can create amazing projects that light up your world. Interfacing LED with Arduino is a fundamental step towards understanding the basics of hardware programming. Which gives a delay of 1000 milliseconds. In this program, we are passing “1000” as an argument to the delay() function. In between these two functions, we have used a “ delay() ” function is used to pause the microcontroller for some period of time during the execution. “digitalWrite(led_pin, LOW) ” makes the voltage on the GPIO pin 3 to 0V. “digitalWrite(led_pin, HIGH) ” makes the led_pin as HIGH means provides 5V at GPIO pin 3. Such as the pin name to which the LED is connected and the state of the pin. In this function, we have called a function “ digitalWrite() ” in this function, we pass two arguments. Void loop() : This function executes infinitely in our program. In this function, we are passing the “led_pin” as pin name and “OUTPUT” as type. ![]() The pinMode function is used to tell Arduino, that the connected peripheral is either input or output peripheral. In this function, we have called a function called “ pinMode(led_pin, OUTPUT) ”. Void setup() : This function executes only once in our program. We are assigning GPIO 3 pin of Arduino to connect LED and given a name to that pin as “led_pin”. Arduino Kits Files Download Laser Engraving Files Download Affiliate Program. #define led_pin 3 : First, we have declared a pin name and pin number to which we are going to connect the LED using #define preprocessor constant.

Once, the Arduino IDE is installed on your PC, we have to write a code to blink an LED in the interval of one second. Light Cube Kits Developing and Providing Worldwide With IC Accessories, Raspberry Pi, Robots, Arduino compatible Dev. You can download and install Arduino IDE suitable for your computer OS from For programming our Arduino to blink an LED, we need Arduino IDE to be installed on our PC. ![]() Make the connections as per the circuit diagram shown in the above image. In this blog, we will blink an LED using Arduino. ELEGOO Upgraded 37 in 1 Sensor Modules Kit with Tutorial Compatible with Arduino IDE UNO R3 MEGA2560 Nano Updated from the old version (others): Received great ideas from our customers and adopted in this upgraded kit. LED stands for Light-emitting diode. An LED is a device that produces light whenever current is passed through it. Buy Duinotech Arduino Starter Kit include LED Resistors Switches Potentiometer Buzer at Australias best store for tools, auto, safety & workwear. Arduino (You can use any Arduino board for this project) - 1įor interfacing an LED with Arduino, we need the above-mentioned components and connections have to be made as per the circuit diagram below.Hardware Required for interfacing LED with Arduino: In this blog, we will see how to interface an LED with Arduino. ![]()
