KEYPAD ARDUINO PROJECT



In this project, we made a keypad passcode that when you type the password in the keypad a green led will light up. If you write the wrong password in the keypad the red led will light up.
Now we will show you how to put together the project. From 2 to 9 this is supposed to be for the keypad and 12 and 13 are for the red and green LEDS then you connect the ground. and don’t forget to connect the ground to both parts of the breadboard.

We built this using 2 LEDs, a keypad a breadboard and last is the Arduino. We wanted to add more into this project though so we decided to make an app that can be used to unlock and lock using an android app you can download it from here

so now as you can see in this picture this is our android app that we created.
