Android tablet and stepper motor
Basically all hardware remains the same as in OpenWrt antenna rotator , one difference is software on a router.
|Remote control in action.|
Additional software is running on tablet, witch is collecting data from accelerometer and send over socket to router. Router analyses data and sends appropriate commands to RS232 Stepper motor control (attiny2313) by serial port.
OpenWrt is running in client mode, and it is paired with my home router, so everything (except power cord from openwrt) is wireless.
