Newbie level 5
I'm looking for some help designing the following circuit. I've done a few hobby level circuits based on the PIC 16F877 / 84 and assume this will probably require something along those lines.
Functional goal description:
Vibrating motor that gives a quick pulse (< 1sec) every 15, 30 or 45 minutes. I'm looking for one momentary-push button that controls the circuit ON/OFF as well as the interval. IE. Push the button once, the circuit turns on and interval is set to 15 min. Push again, interval changes to 30 min. and again for 45 min interval.
It's a 3-5v dc motor and I'm assuming I can run it at line level. As you see I don't have a lot of knowledge around this yet, and would appreciate any help I can get.
Thanks a lot!
