I'd like to use 5 hacked (360° Degree) SG90 - Tower-Pro - Servos on one Channel of the Arduino Nano v3.
(should I use PWM or direct 5V to the DC Motor and cut the board with circuits out? )
I'm thinking about using a NPN Transistor
instead a Relay (Vout on Channel and Iout is to low/less then needed)
so how must i build it on a breadboard?
do I need a low NPN which is switching a bigger Darlington NPN ?
do I need Resistors? how big? how many? or do I need other things?
