I'm currently building my first car project using L293D. I have done few basic examples and everything works fine.
Items:
- L293D
- 4 DC Motors
The problem is that the shield isn't passing any power using the M1/2/3/4, which will be used to power up the motors.
I have tried connecting an external power supply to the shield directly and the LED did light up, nevertheless, no power was passing.
I'm using a breadboard with a LED to test for the electricity. It's not lighting up and even the motors are not running when using jumpers from the M1 and connecting them directly.
Image of the setup is in the attachments.
I have tried switching the jumpers and switching the poles because I thought i have connected them in a wrong way.
The Arduino UNO is working fine and I'm able to upload sketches.
