Hello ET,
I am building a lightweight robot using the Tamiya 70168 dual motor/gearbox combo. The motors will be running at 3v provided by 2 AA batteries. They have already been measured to pull 2.4 amps each at stall. I would like to use an H bridge circuit to control the forward and reverse functions, rather than use relays, to keep the size and weight at an absolute minimum.
My question is: would ET recommend building the circuit myself with transistors and if so, what types, or, would using an H bridge IC, like an L298, work best? Also, what other components will be necessary to make this work? Using a logic board like Arduino is not allowed either. My knowledge on this topic is limited so any and all information is appreciated.
Thanks,
Matt
