Blinking LED using Arduino

Beginner’s Guide to learning Arduino-Technology

Arduino UNO is a microcontroller board- it is the brain of any electronics project. In the following project, we will use Arduino UNO to blink an LED and give a visual demonstration of how high voltages can fuse the LED.

Setting up Hardware:

Components Required:

1. Arduino UNO
2. Arduino Cable
3. BreadBoard
4. LED
5. Resistor
6. Jumper Wires

Assembling:

1. Connect pin 5 of Arduino to Anode(+) of LED, which is longer lead.
2. Connect resistor’s one lead with the shorter lead of LED, and the other lead to GND (Ground) of Arduino.
3. Connect Arduino to your Laptop using Cable.

Setting up Software

Copy-paste the given code on Arduino IDE and upload it on the board.

Watch Complete Project Video:

ALERT! Don’t Fuse Your LED

LED will fuse if you provide it a high voltage of 3.3/5V directly from Arduino. Let's see how it fuses in the following video:

DON’T TRY THIS YOURSELF, YOUR CIRCUIT MAY CATCH FIRE.

Conclusion

Congratulation! You have successfully build your first Arduino project. It’s your 1st step towards mastering Arduino projects. To learn more about Arduino boards, setting up Arduino IDE, and step by step visual demo of the blink project, watch our video:
