I am working on an antenna rotor, that will move my antenna array around at any azimuth (0-360 degrees). To insure accuracy i am going to use this Adafruit HMC5883L Breakout - Triple-Axis Magnetometer/Compass Sensor to report the azimuth and eventually elevation the antenna array is pointing.
As a motor, I want to use a wiper motor. This is because i will have 4 antennas on this project, the rotating mass might be around 5 pounds. A wiper motor seems to be perfect for this.
But a wiper motor is just a DC motor? Can any DC motor controller run this? I need one that is bi direction. I figure the motor i want will be around 10 amps, so i need to find the correct controller the allows the much current.
Anyone have any thoughts on this? For control, i have a program written that communicates with the arduino uno via serial connection, and will have 5 check points during a satellite pass, so that i dont have to go outside and move it my self.
