Blink LED with Arduino - Tutorial with Circuit and Program

 Introduction:

                         Welcome to the LED Blink Project using Arduino, a programming board that operates based on input programs. The fundamental Arduino program for beginners is the LED Blink Program, making this project incredibly simple. Let's explore the steps on "How to Make this Project" below.

Connection:

         To begin, take the Arduino Board and place it on a DOT Board or Bread Board. Use wires for the connections, and fit a 5mm LED on the Bread Board. Connect the LED's positive (+ve) end to Arduino's D13 Pin and the LED's ground to the Arduino Board's Ground. Connect the power supply's positive (+ve) to the Arduino's Vin Pin and the power supply's negative (-ve) to the Arduino's Ground. With these connections, the circuit is complete. Next, upload the project program to the Arduino Board. Let's see "How to Upload the Code to the Arduino Board."

Code Upload:

               After completing the circuit connection, install the Arduino Software on your mobile or desktop. You can find the software link in the I2C Module Connection Article. Open the software and connect the Arduino Board using an Arduino cable. In the "Tools Menu," select your board name and the board's USB port. Click on the Example Program and choose the Blink Program. Then click the ⏩ symbol to upload the program to the Arduino Board.

Working:

                  Once the program is uploaded, the LED starts blinking with a specific time delay. The project's functionality is dependent on the time delay specified in the input program

Part List:

1)     Arduino Board =1 (Arduino NANO or UNO)

2)     5mm LED =1

3)     220Ω ¼ watt Resistor =1

4)     Arduino Board Cable =1

5)     Bread Board or DOT Board =1

6)     Some Wires =1
