I want to use the setup in the pic to control servos, this pic shows 1 servo I want to run 4 servos, how do I change the sketch to recognise and work the 4 servos and work out which extra pins to use for what, I've been looking at loads of different websites but all I find is loads of pages of text, I learn from watching so all this text is going straight over my head, im at the stage of giving up with Arduino and finding another way to do it.
If you attempt to power 4 servos from your 5v pin you will shut down the arduino. That pin cannot provide the power that motors consume.
Even one servo can pull too much current if you make it work (attach anything to the servo arm).
Much better to power servos from an external source. Connect the grounds.
Without the button or LEDs, have you tried following the servo sweep tutorial? It is pretty easy to modify that to work with multiple servos. Give it a try. Let us know if you have questions.
