started with PIC16F84 2 weeks ago, my first circuit was an the pic hooked to a LED decoder and a LED display, it increments every 1 second when a switch is closed, or it decrements every second if the switch is open.. so with my knowledge or little more, im supposed to make a project. any IDEA's..? suggestions? so far on my list is a volt meter, maybe a traffic light controller with a finite state machine running it. any other suggestion for interesting and challenging projects to work on.? not a really big project, should be done in 2 weeks..
