Hello,
I am new to circuit design and very much a novice and am trying to get my head around limit switches.
I'd like to make a belt drive system that is powered by a DC motor. The motor will turn in one direction until the belt reaches a certain point (hits a limit switch), and then the motor will turn in the other direction (until that limit), and so on. I was planning on fixing some sort of plate onto the belt itself to act as the contact with the two limit switches. There would also be a basic on/off switch for the whole thing.
I don't really want to use a microcontroller as I want the system to be as reliable as possible since it will need to be running for a number of weeks.
I think I've just about got my head around DPDT latching relays but I'm unclear how to reverse the polarity to the latching relay using the limit switches, to energise/de-energise the relay and reverse the polarity to the motor.
I'm aware there are a lot of threads relating to similar topics, but I'm unclear about the variations of each one and what's the best approach to take in this instance.
Any help or advice or just general chat would be greatly appreciated.
Thank you in advance.
