Access control with Arduino plus Keypad 4×4 plus Servo




Hi guys, I bring a new instructable for arduino, the control access with password, 4×4 keypad and a servo.

We will use the Password and Keypad librarie for arduino, besides using the servo library, but this project can also be modified by changing the servo, a motor reley or motor stepper, or any other ideas …

This project can be used in different cases, for doors, Servo action, etc..

Step 2: Preparing the keypad

Well, now we must put the resistors,remember the potion of the pins of the keypad.

Output pins of keypad:

1 pin = col 1
2 pin = col 2
3 pin = col 3
4 pin = col 4

5 pin = row 1
6 pin = row 2
7 pin = row 3
8 pin = row 4

(look at the second image)

Now they must put three 910 ohm resistors on pin 1, 2 and 3 of the keypad, then put in the arduino digital pins of the NEXT form:

pins keypad  |  pins arduino
—————————————
1           |           8
2           |           7
3           |           6
4           |           9
5           |           5
6           |           4
7           |           3
8           |           2
