i am having issue getting this servo to continuously rotating
its currently running with 0 load from the 5v port off the arduino, i also have a PSU for my breadboard which is also 5V
no matter what code i try i can not get the servo continuously rotating
dose anyone have any experience with the FT6335M
Regards
Matt
For heavens sake abort that doing before You burn the Arduino, if it's not already crippled.
Never power such things from any Arduino board!
Yes, 5 volt... Have You ever heard about current, amperes? Those tiny copper strips on the board are dimensioned for milliamp currents.
It’s now being powered by a 7.4 supply but still no luck
What kind of supply (current capability).
Did you share grounds.
Code and a picture could help.
Leo..
I’ve got an adjustable psu
The common ground has been shared from the arduino to the breadboard
I’ll upload the code and a diag when I get home
More than luck is needed. Please post schematics. Pen and paper is often good enough.

basically i want to turn the encoder to select a number
you hit enter and the servo turns untill X number has been reached
im trying to load BBs into airsoft magazines
