can i connect a servo to the 5v on the arduino? (2560)
I dont own an oscilloscope, so i dont know if its dragging the 5v down??
Thanks for any leads!
No, provide the power for the servo from a separate source capable of 1A per servo.
Don't forget to connect the grounds.
Do you own a DMM?
What sort of servo? Some of the bigger ones will kill the regulator in the Arduino more or less instantly.
So you should use a separate power supply to the servos, e.g. 4 x rechargeable AAs. Connecting to the 5V pin is a bad idea but it can sort of work if you have one very small very lightly loaded servo.

A volt meter will tell if you are dragging it down. Also if you put your finger on the regulator and it smokes you have an overloaded regulator and a burnt finger. This response is to help you get started in solving your problem, not solve it for you.
Good Luck & Have Fun!

Not always, drop outs can be milliseconds in duration and not affect a slow responding multimeter
(most multimeters use dual-slope integrating ADCs which have a bandwidth of about 1Hz and thus
don't see rapid change at all)
