4 ALARM SOUNDS using PIC12F629

This project is a miniature 1-chip alarm. All you need is a tilt switch, battery and piezo to produce a complete alarm. If you want a very high output, you can add a Darlington buffer transistor, piezo tweeter and a 10mH choke. The chip does all the work. It sits in sleep mode (100 microamps) and waits for the enable line to go high via the tilt switch. It then produces a SPACE GUN alarm for approx 3 minute ...

Single button code entry for a digital lock using PIC16F628A

The Button Code is a system that allows a single button to act as a keypad. The user enters a 4 digit code into the system using button taps. The button can be placed where the public can access it since like a keypad there are many combinations to keep guessers from activation the system. When the correct code is entered a form-C relay is activated (Normally Open and Normally Closed relay contacts). When a ...
