Hey guys, i have an Arduino Mega, and after running through a lot of the basics in programming the Arduino Environment and Processing, im ready to move on to Servo/Stepper controlling.
a couple of quick questions that i couldnt answer from reading:
Do i absolutely need an H-bridge to control the servos/steppers? ive seen a couple posts where they arent even mentioned, and a couple where they've been said to be necessary.
if an H-bridge isnt necessary, how can i power the servo/stepper externally?
thank you for your help.
