I am making a bluetooth car using arduino and L293D motor shield which is shown in the picture below. I applied various power sources, like wall socket with 9V adapter, 12V from lithium ion batteries etc, I get connected to the bluetooth but the motors are not spinning. I have another car which justs works fine, that is, which uses geared motors and 12V from lithium ion batteries. So I know the code is fine and the connections are also fine. Do I need to use geared motors? All others aspect is the same for the two cars(working and non-working).
Thanks
