Are u sure it will works with that 9V battery ? and how much ampere does it supply ?
Reply 6 years ago on Introduction
It runs for around 15 minutes, and the batteries can supply 300mah(nimh). Li-ion batteries voltage is to low, as it cuts out at about 7.5 volts.

I use two li-ion 4.2 6000mah plus a 9v battery. I power the arduino with the 9v and the motor shield with the 4.2v 6000mah batteries and no problems.actualy the arduino can handle 12v.

Hi!
Can you help me please? I have a problem with the overturning of the program. It's write:
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x00
avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x00
avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x00
avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x00
avrdude: stk500_getsync() attempt 6 of 10: not in sync: resp=0x00
avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0x00
avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0x00
avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x00
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x00
So I can't upload, it's a big problem.
Thanks for your help!

Program get into arduino but car doesnt work :/
I download app on the phone but nothing happen

Oh for me this is the same, the robot not function :/

The wires of mounting must not be plugged in when you put the program on the Arduino board. I think that was the solution to my problem.

The wires must not be plugged in when you put the program on the Arduino board. For me it was that.
Tell me if it your problem :)
