Thanks for the great information. A diagram of what you have in mind would be awesome. Of course, then there lies the problem that I honestly don't know how to read a true electrical diagram -YET.
Is there a layman's way you could diagram this including the 9v battery used for the control power?
At the risk of "wearing out my welcome"
, I have a few other questions keeping in mind that I've never built a circuit in my life:
1. To protect the motors, should I use fuses downstream from the relays?
Fuse goes between the + bat terminal.
2. Is soldering the relays and connections to a proto board recommended?
For this I would try to find relays with screw terminals. Crimp and solder terminals to the wires and screw them to the relays. Not a must. Others may not agree.
3. Should heatsinks be used on the relay board? If so, do you have a recommendation?
Not required for mechanical relays.
4. Are there any other circuit components to consider on the relay board for regulation of the voltage/amps, etc?
Not that I know of.
Thanks again!!!
