Hi all,
Here's my situation.
In it's simplest form I am wanting to drive a 12V DC gear motor that will pull 1.5-2 amps. Once I hit the "on" button, I want the motor to run for 5 sec....stop for 5 sec....reverse for 5 sec.....stop for 5 sec... and repeat (5 sec is somewhat arbitrary).
From browsing the forum for the past day, this seams like it shouldn't be a problem, however, it also seems like there are a million ways to do it. There is just so much info out there, I'm kind of getting lost.
From what I've gathered I need 2 signals, call them A & B. I should be able to set things up to where if A=High & B=High, motor turns clockwise. A=High &B=Low, motor turns left and A=Low & B=Low motor off.
Now here is where my total lack of product knowledge comes in. A popular option seems to be a PIC and an H-Bridge. Using google, I find H-Bridge Chips and I like the idea of using as many integrated parts as possible, i.e. use an H-Bridge chip rather than making the circuit if possible. However, I'm not sure if they make heavy duty enough chips to drive a motor that will pull 1.5-2 Amps.
So this is where I ask for advice. I'm planning on getting a PICkit2 or 3 for the programming. With that knowledge, what micro controller would you start with, and how would you build the system. Heck, maybe I'm over complicating things and I can get away with a simple logic circuit, I just don't know enough about what's out there.
Thanks for taking the time to read, I appreciate your help.
