Edited:I have charged the robot and now it won't do anything and the light isn't on

How do you know that it is receiving commands ?

I think that means the battery is running low.

I can see that whenever I use the app the tx and RX light on the arduino light up

Hi,
Do you have a DMM to measure the battery voltage?

Thanks.. Tom... :smiley: :+1: :coffee: :australia:

Is the red light still flashing?

8

yes, its intermittent

yes, I have a dmm and its around 8.19 volts

Hi,

If that is plugged into the DC socket or Vin then you may be having regulation problems.
The internal 5V regulator will only just work at 7V, if the 7V drops so does the 5V to the controller.

What is the battery that you are using?

Thanks.. Tom... :smiley: :+1: :coffee: :australia:
PS. I'm off to bed, goodnight. :sleepy: :sleeping: :sleepy:
