I recently finished my very first line follower. When I was ready to test the wheels it turned out they wont move at all. I have L293d motor shield since I am completely new to this I looked up few tutorials so find out what parts to go with. I now know it was not a wise choice but its a bit too late. I have 4 AA 1.5V batteries to run the motors and 9V to power the arduino. I included the picture of the motor shield with the motors connected. When I switch it on I can only hear some sounds coming from the motors (the classic dc motors that come with every line follower kit) but the wheels are not actually turning. I did try stronger batteries but that resulted only in brighter green light
So basically, does anything look odd about the connections or could it be the standard voltage drop problem that Im facing here? If so what could I do about it?
Thank you for any advice
