First project RC car won't move

Projects General Guidance
1

This is my first Arduino project as my school lent me one to do something with.

I followed this guide to create the car:

Everything works fine because if I lift the car in the air the motors spin correctly. Only when I put the car on the ground do the motor do nothing, they make a little sound but that's it.

All I can think is that it is a problem with: Grip on the wheels; Too weak motors; Not good enough of a battery. I am using a procell 9v battery if that is any use.

Could anyone give me any advice on this?

We'll need a wiring schematic. You're probably trying to power the motor through the Arduino which won't work.

The wiring schematic is on step 4 of the site I linked.

I will try using the 6 AA batteries thanks

(not sure how to quote things on mobile right now or link an image from the site)

On pc at least, highlight the text and a QUOTE box pops up above the text. Also, you can copy paste images inline.

Also, please take a look at getting the best out of this forum. Things like putting the wiring diagram directly in the post will help you get better answers faster.

Thanks, I'll try to use PC or figure out how to do it on mobile if I need to post on the forum again.
