Turn on 7-segment Led by Keypad

In this project I'll explain you how to turn the desired number in LED display by using keypad.

Apparatus:

• Keypad
• Arduino uno
• Jumper wire
• 7 segment led

Step 1: Assemble the Circuit

connect 4 row to arduino's digital pin 2,3,4,5 and coloum to 6,7,8.

for display connection

• Connect "a" to digiatal pin 0 of your Arduino board.
• Connect "b" to digiatal pin 1 of your Arduino board.
• Connect "c" to digiatal pin 9 of your Arduino board.
• Connect "d" to digiatal pin 10 of your Arduino board.
• Connect "e" to digiatal pin 11 of your Arduino board.
• Connect "f" to digiatal pin 12 of your Arduino board.
• Connect "g" to digiatal pin 13 of your Arduino board.

Step 2: Upload the Code

Upload the above code to your Arduino board.

Step 3: Try It

Lets give input from the keypad and check it whether it is working properly or not.
