I have been reading this forum for the last 2 days and while being more informed about stepper motors and drivers and 360 degree servos, I am also more confused on what to do.
I need to get a servo or stepper motor to turn a gearbox control shaft in a rc car 360 degrees in 60 degree intervals, both ways.
The setup will be controlled by a 3 position on/off/on momentary switch on the Tx - if I trigger the switch in on direction the servo/motor must move 60 degrees in one direction and stay there. Trigger the switch again in the same direction and the servo/motor moves on another 60 degrees. The same will be true for the other direction. So this means I will be using the Hi/low value from the rc channel to determine direction.
From what I have read here, a servo modded for 360 rotation will not work as it will not give you you precise stops - which means I will have to go with a stepper motor.
My question to you guys please:
are these the components I will need for this project?http://www.pololu.com/catalog/product/1202http://www.pololu.com/catalog/product/1204http://www.pololu.com/catalog/product/1615http://www.pololu.com/catalog/product/1210
Also, the motor must stop when reaching 360 degrees and only be able to move back to 0 degrees in reverse steps, stopping at 0 degrees again.
Any help and ideas welcome and appreciated.
