The button code project designed by Alan Parekh is a PIC 16f628A microcontroller driven single button code entry mechanism that has a retro feel to it. The main stand out point of the project is the single button which acts as a keypad for a four digit code entry using button taps. This straightforward circuit can be used as a controller system for garage door openers, toggle to turn-on & turn-off lights, door access or a simple security system for homes. The system has lots of options to toggle around with like slight changes in the code, activation time changes, different operating modes and much more. Take a jump for the detailed video of the project.
