The project aim is to build a better kitchen timer. It has four independent count-up and count-down timers, display of current value of user-selected timer, start/stop and digit entry controls, and alarm buzzer.
The project uses PIC16F877 as main processor. The output part consist of single 7-segment LED display and piezo speaker, while the input part consist of 10-position “BCD” rotary switch, two pushbuttons for set and start/stop, two 8-position DIP switch for timer selection. The project software written in PIC assembly and compile it using gpasm. To write the PIC, it uses XWisp and WLoader.
