Hi, the chip is a L293DD, it's not getting hot at all. I have tested the signal into the L293DD when the delay is happening and it has no signal so I am thinking that the L293DD maybe ok? or could it be that the L293DD is burned and the signal needs to build before it flows? I am thinking like a plumber with a blocked pipe
I don't get why the fault only occurs when I move one particular motor to the right on it's fastest speed. Its like it's stealing all the power from the board and the components need to recharge before it starts up again
