Hi All, My first post!
I need to reverse the direction of a small DC motor, 12vdc 500ma, when it (the load) comes to the end of it's travel. Think car windshield wiper, but solid state (OK it can use a DPDT relay).
I don't think I need to apply a micro to this (not so good at them anyhow).
I'm thinking some sort of current sensor (op amp?) that see's when the motor hits the end and senses the current rise, this could activate the relay and reverses the polarity so the cycle can repeat.....
Being adjustable would be helpful, so that it can be tuned in.
Any advice would be appreciated.
Thanks,
Steve
