Hello there, the diagram shows 2x 12V, 7A motors beeing controlled bei 2x IBT_2 drivers.
The problem is, that both motors beeing controlled by 1 driver and I dont know why. For example I could run them the same direction. If I put a 255 PWM signal to both drivers, they both run then I cut the power supllie of one driver and they both still run but a bit slower. I could run the motors seperatly, they drive the same direction even if I send a 0 PWM signal to one of them. The interesting part is, that this doesn´t happens with smaller 12V motors. They work fine and react to the PWM i give them individuelly. So I guess the problem just appears by big motors with high A usage. Do you guys have a soulution for my problem? Thanks
I am not sure your wiring diagram is incomplete you are missing power and ground to the IBT-2 and some other connections. I cannot read the picture. A real annotated schematic would be much easier to follow. Also your 9V battery will not last very long.
Connecting this part wrong can damage it.

Have a look at it again, IBT_2 has Power supply. VCC and GND is conected to the arduino. Also the 2x Lipo supply the Motors. The 9V block is only for powering the Arduino and IBT_2, but not for the Motors.
