Attempting to build Arduino Based Antenna Rotator.

Arduino uno flashed with GRBL Firmware v0.9. To control antenna rotator I am using G-Code Sender GUI open source software(many different one available on web) .Possible in the future custom GUI will be used.

Here is the screen shoot from G-Code Sender GUI
