I forgot to add some info about using an H-bridge.
An H-bridge would just be a current flow controller that switches the polarity of two points on the bridge. In one output condition the +output would simply forward bias a diode that would enable F1 transmission with F2 transmission turned off due to a reverse biased diode. Switching to the output of the bridge would then reverse bias the F1 diode and forward bias the F2 diode. Both F1 and F2 can be turned off by the third state of the H-bridge, both outputs turned off so nothing is transmitted.
Yeah, I've seen it called push and pull transistor state.
In a motor, one half is to drive the motor forward, and then other half is to reverse the motor.
So if I understand it right, in my case it would be to make positive and negative pulses?
