Can anybody point me in the direction of a circuit diagram displaying the use of transistors as a switch in a situation which allows me to drive motors back and forth.
I am having difficulty understanding how to implement independent power supplies for my motors. (e.g how to allow the use of transistors in a situation where the polarity is reversible)
The RF unit i am using acts as 2 DPDT switches, I would like for this to switch the transistors, allowing a larger 6v supply to drive the motors. This appears to me to be pretty simple if driving the motors in one direction, my problems start when trying to complete a circuit in both directions as the transistors won't allow for the current to travel in the opposite direction when it is reversed and + becomes -.
I imagine i would need 4 transistors (1 for each wire from the RF unit)
I hope this is understandable as i am obviously fairly confused about it.
I appologise for my ignorance in advance. Any help would be appreciated.
