Hello,
I am new-ish to the game and I have run into some trouble trying to set up a timer circuit.
My goal is to have a high output duration of around 20 seconds every 4 or 6 hours. Accuracy is not a concern for me as I am using this circuit to empty a dog bowl.
At the moment I have NE555P, CD4017BEE4, CD4020BEE4 & CD4060BEE4 in my draw. I think that the 4060 will serve the purpose, though i'm not really sure, I am a bit lost looking through all of the data online. There seems to be a million different ways to do this and I just can't get my head around it.
This is my current set up (about 11 seconds high at the moment)
Any help would be greatly appreciated.
P.S. I also have the MSP430 launchpad with some additional IC's. I intended to use this, however the programming is entirely over my head also. I am thinking that using analogue IC's to start with would be a good base to work from when I start to learn programming down the track.
