Hi, I’m completely new to the arduino and I decided to start doing a car.
I bought a 4-wheel chassis kit, plus the arduino uno and a motorshield l293d.
The problem is that my engines are not spinning, they only start to spin if I “push” on the tires of the car, then yes they start to roll. And if I lean the cart on the ground they stop again.
I did the test by connecting the motor wires directly to the battery and they spin perfectly, so the motors are not the problem.
PS: I am powering the arduino through the p4 port using a 9v battery. Just like another 9v battery to power the motorshield.
Please save me
