Hi! I am trying to figure out a problem about Dual h-bridge (like the one I’ve attached) which controls two TT motors.
I connected the dual h-bridge to Arduino UNO.
Initially I powered just the Arduino by a 9V battery and I connected the dual h-bridge to the 5v port, but then I changed my mind because the motors received little energy, therefore they moved slowly.
(PS The motors worked perfectly)
Consequently, I decided to power the dual h-bridge separately by an other 9V battery. (I connected the dual h-bridge directly to the battery, without any resistor).
I uploaded the same code as before on Arduino, but I realized I can just move the motors simultaneously: when i try to move one motor at a time, both of the motors don’t move.
How can I solve this problem? I need your help.
PS I’ve attached the code I am using.
