Electronics Coursework

[templeman]

Im having serious trouble finding a project for my A level coursework. the boundries are simple it has to be based on either control systems (i.e using a PIC) or communication

i would preferably use a PIC but another boundry is that it has to include 3 active devices such as IC's, transistors and aparently diodes.

It doesnt have to be complicated but as easy as possible

thanks in advance!
