I am trying to use eight 4.8V SG92R servo motor with my Arduino, but I can't seem to power them correctly. I have tried one 9V battery for every two and splitting the voltage with two 100 Ohm resistors, and 4AA batteries (6V total), but nothing works. I don't have enough time to order any new parts.. my competition is this Saturday! Please help.
Because the servo comes from the RC world it is ok with 6V. Connect the servo +ve (red wire) directly to the +6v, and the ground wire (brown) to the -ve of your 6v. Also make sure that the brown wire connects to the Arduino -ve, and the PWM wire (orange) to the signal out of your Arduino. DON'T drive it with 9v! (100ohm or not) you run the risk of killing the on-board eletronics. Yours Simon M.
