I want to make a wheelchair controller.but I try in my arduino tank first. power is 4 AA battery and motors are tank motors.I use its shield and combined them.there is only one joystick in the analog pins and 5v gnd standart.
when I connect the power, the light of power starts to work. but motors and their lights doesn t work.
You will have to provide us with better information.
A wiring diagram. Pencil, paper and a camera are just fine.
Pics of the actual project often help.
Here is a handy image guide to help you post the images.
A photo and a video both without identifiable part numbers? That's not exactly useful to us.
We need the website link with the datasheet or other product information - as much information
as possible.
And what motors? We definitely need to know about the motors.
"Please give full details of all the hardware so we know what you have..." that doesn't mean a few scraps.
The LEDs on the Sparkfun shield work best when your power supply is 12V. They should be visible with 4AA's as the power supply. The LEDs are directly across the motor output terminals (with resistors) so they should always indicate the state of the output.
