Ardumoto and arduino

Hi there :)

 

I have a simple problem... I combined Arduino and Ardumoto.

Now I have 6x 1.2NiMh  AAA batteries of 800mAh each... I charge them up.. it shows 1.2V when I measere them but when I connect to arduino it says 6.3 or something... well, which is enough... theoretically

 

Now my problem is that sometimes my Arduino just resets if I pull strong of the motors... with a simple 40 pwm no problem... with 255 it resets...

what can I do?

 

should I go for AA? or 2x9V in parralel with 5V regulator?

Why are you running your

Why are you running your motors from a regulator? That is not the way. Always drive them direct from battery source. Also I hope you are using a h-bridge or some form of transistor drive.

Ardumoto is a L293N shield

Ardumoto is a L293N shield for arduino so it’s not a problem of shorts here…

 

I think the robot is the one who eats a lot of battery… still my question remains guys

should I drive 2X 9V battery in paralell to the robot?
