how do i reverse polarity to/control a "hobby" servo using an arduino chip and motor shield? Answered
i am new to programing and electronics/circuits i.e. breadboards etc, and i have been looking around on this website and YouTube to reverse the polarity to a linear servo motor to make it go forwards and backwards. i am also having with the servo going to far forwards and backwards and locking up the motor to the point where i have to manually spin the gears to free the motor, how do i fix this?
The servo/motor i am using is a AS2000L 1.7- Gram Linear Ultra-Micro Servo and i am using 2 types of this servo, one with just positive and negative wires and the other is the full version with the chip and receiver/transmission wire here is the link for the servo,http://www.spektrumrc.com/Products/Default.aspx?ProdId=SPMAS2000L the specs for it that are on the back of the package are:
Torque: 2.8oz of force
Speed: .14 sec @ 3.7V
Dimensions: 22 x 16.9 x 8.2mm
Voltage Range: 3.2V - 4.2V
Connector Type: JST
In the beginning i used a 9V battery and just switched the ends that the wires touched and that was how i was reversing the polarity, now i am using the same method but with 3 1.5V AAA batteries connected together.
