Was wondering why my servo wasn't following the potentiometer properly, not going the full 180, erratic buzzing blah blah blah, all the usual symptoms.

Much scratching of head..... flaw in the code?... fried servo?... flat batteries?

Nope, I forgot the Arduino / breadboard / servo ground wire.

I play a lot with servos, so I designed my own board to make it more easy to test code and connect servo to the ATmega328. http://www.bajdi.com/bajduino/bajduino-3a-3/
It has 3A switch mode regulator so it can power a couple of servos without trouble. Has 3 rows of male pins for every input/output.
