I have 4 Tower Pro MicroServo 9g SG90 I want to power with a battery. This is the datasheet I found online.
I have a small breadboard and some resistors laying around (220, 1k, 10k), and a 9V battery.
I hooked up the battery leads on the power rail of the breadboard, and added my 4 servos in there, and they turned on and rotated properly when I issued commands from my Arduino board. The thing is that AFAIK it operates on 4.8V-6V from what I have read.
I did a voltage divider using some of the resistors I had and I could output 5V when tested with my multimeter, but the servos didn't work (probably because low current).
So my question is, can I power my 4 servos with a 9V battery? Should I add some resistors before? Bear in mind I am new to electronics.
