Question

This question is about the Arduino code.

Please complete a 4-input circuit on your Arduino. Your circuit, in addition to cycling through a binary representation of the numbers 0-15 using LEDs, should use the Serial port to output the decimal equivalent of each of the numbers in the format:

Output: 15

... if the value was 1111, and so forth.

You will be asked to upload your code as well as a photo of your working breadboard circuit.

Add comments to your code as needed.

Thank you...

Circuit description :

1. I have used Arduino Uno board.

1. 4 LED’s , each have one positive terminal and negative terminal.

1. Connect those negative terminals ( of all 4 LED’s ) to Ground.

3.1 First , place all the 4 LED’s on bread board , then connect ground of Arduino to bread board. Make sure You connect all the negative terminals of LED’s to that ground.

1. Connect positive terminals to arduino

4.1 Then , connect 4 the digital pin on Arduino to anyone LED positive terminal

4.2 Then , connect 5 the digital pin on Arduino to anyone LED positive terminal

4.3 Then , connect 6 the digital pin on Arduino to anyone LED positive terminal

4.4 Then , connect 7 the digital pin on Arduino to anyone LED positive terminal

1. Upload the code to arduino IDE and dump it into Arduino board.

1. Open Serial monitor , there you can see your output.

THANK YOU !! If you have any doubt regarding this question , please comment.
