Once built this timer board can be used with your choice of 8 pin PIC processor and flowchart software. It’s compatible with, most educational PICs & software. The kit has a start switch as well as LED & sounder outputs. Programming is via a 3.5mm jack interface. Processor not included.
Four tasks have been devised from a basic timer, to one where the delay is configurable by the user, it warns that time is almost up and then plays a tune upon time out.
Please see the timer tasks resource page for full details of these tasks and to download programming guides and example tasks.
