hey guys, I need some advice here:
I connect several servos to my arduino, as follows: the arduino powers through a 9V battery (using the power jack), and the servos power through a 5V (3Amp) external power supply. all gorunds connected together.
the project runs nicely for a while, and then the servos halt.. when I touch any wire leading to any particular servo with my bare finger - it suddenly goes back to life! (for a while). this is not due to any loose connections, as it doesn't happen when I touch the wires with some stick.
I guess it has something to do with static charges that were built somewhere. sounds familiar to anybody ? any suggestions?
thanks in advance, Rubin
