Hello.
I'm currently building a RC robot using PT2262 and PT2272-M4. I'm having trouble with controlling the DC motor using L293D. The motor keeps turning on and off while I connect the input pins on L293D to PT2272-M4 data pins. The supply voltage for L293D is 9V and I'm using 5V for the enable pins on L293D. I followed everything as stated in the schematics. Can anyone tell me what's the problem causing it?
The schematic:
p/s: I've changed the HT648 into PT2272-M4
