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

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.

Upload the above code to your Arduino board.

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