Pin Pad Servo Lock With Backup SoP Unlock

My inspiration behind this intractable what's the create a final project which Incorporated two units that I have been covering throughout the semester and to emphasize them more, the two units that I had chosen were unit number two microcontrollers and unit number one computer hardware.

this project had some inspiration come from intractable wish I had seen where somebody had created a keypad light bulb system were they were able to turn on a light bulb by entering a certain code into the keypad, what I had done after that what's compile code end link it with a Servo motor and a sop( some of products) to have a backup switch along with a code.

Step one create a sop circuit follow wiring to-a-tee

step 2 wire lcd screen to Arduino

- purple=input

red=power

black=ground

step 3 wire pin pad to Arduino

-light blue and yellow only

step 4 wire servo motor to Arduino

-red green and black only

step 5 connect LED (master) to pin 13 or any pin of choice

-Long purple wire
