I've got an old rc car laying around, of which i would like to swap the insides, but re-use some of the parts that are already in there. The car runs 2 dc motors: one for steering, one for throttle. The dc motors are both connected to H-bridges in the original setup to make their direction switchable. This is done via 8 transistors. 4 for the throttle and 4 for the steering.
The transistors for steering are 2x S8050 (NPN) and 2x S8550 (PNP). For throttle it uses 2x 2SD882 (NPN) and 2x 2SB772 (PNP).
I found a schematic in an online post of a arduino H-Bridge setup. It look promising, but it uses 2n4403 and 2n4401 transistors. I was wondering if I could copy the schematic, replace the Arduino 5v power source (as depicted in de schematic) with the battery voltage source of the car, and replace the transistors in the schematic with one pair of the transistors I described above (so 2x 2SD882 and 2x 2SB772 or 2x S8050 and 2x S8550) Would the arduino be able to switch the described transistors? Would the 1K ohm resistors in between the arduino and the transistors suffice?
I am planning on making this schematic twice, once for throttle and once for steering. The throttle output is max 11.5v and the steering uses around 5v. Therefore the throttle circuit would be powered from the battery voltage and the steering circuit would be powered of a 5v regulator.
Can this be done this way?
