I would like to control 5 or more linear actuators (with potentiometers) using a single motor driver and power supply. (to keep costs low)
Power supply Around 12v 6 amp
Motor controller Pololu High-Power Motor Driver 18v15 http://www.pololu.com/catalog/product/755/
Actuators http://www.servocity.com/html/25_lbs__thrust_linear_actuator.html Operating Voltage: 6.0-12 Volts DC Current Drain (12V): 800mah operating No load Current Drain (12V): 3200mah operating Max load Potentiometer: I0K
I only need to move one actuator at a time. Just direction and position. Speed control not needed.
Is it possible to connect all actuators to some kind of "switch box" that the Arduino could control and monitor?
The idea being:
actuator #1 change direction, watch potentiometer, stop on specified value
switch to actuator #2 change direction, watch potentiometer, stop on specified value
Then the next one and next one.
Thanks for any help : )
