Hello, I am new to electronics so I'm a bit lost when it comes to servos + how to control them.
Here are my 2 questions:
1 . In my project, I want to control 50 Tower Pro Micro servos S90 (9g) with the Arduino Mega. The manufacturer did not give specs about the current output of each of the servos so I'm not sure if I would need an external power source. A friend told me that I may not need external power at all because each of the micro servos draws so little current. Frankly I don't understand this, so I'm asking for verification.
2 . If I do need one, my initial sketch is to connect each servo to a MOSFET and a 1k resistor, then connect all to a 9v battery, but this would make assembly even more tedious. What is a smarter way to do this?
Thanks in advance!
