Timing circuit - how to
I am a NooB to electronics and instructables and would like to build a time control unit. What I am looking to do is build an auto baster for my smoker. The idea is to have a pump (ac pump or possibly a dc washer motor pump not sure yet do to the pressure needed) connected to a copper tube that runs the length of my smoker. I want to have a time control circuit connected to the pump where I can adjust the A) interval in which the pump is triggered B) the length of time the pump runs for. I have never done anything with electronics; well besides some radio shack kits as a kid however I do have some basic understanding. If anyone could help me or even just point me in the right direction that would be great.
