Hello Friends, I am using a 12V 1.5A power source to operate a stepper, bump switch, and two servos based on the circuit design below. I have managed to get the stepper working correctly with the switch. However I am not sure if the servos are connected correctly or if any addition components are required e.g. transistors, capacitors, resistors, etc. I would greatly appreciate any feedback.
1.5 amps might not be enough for the servos and motor if they all start up or change direction at the same time or if there are any significant loads involved. You will most likely be ok, but if it behaves unpredicatably or the Arduino resets, you need more amps.
See the links in my signature for some servos pulling 1+ amps under load
