+#Description:
+
+This is my second prototype of automated Barn Door Star Tracker. The first one made of wood and screw was a total failure due to the imprecision while aligning the motor to the shaft and due to the weight.
+
+
+#Goals:
+
+1-Automated.
+2-Cost below 20$ in part.
+3-Run on batteries
+
+That created some constraint on the possible solutions. I had to reduce the size of the motor, so use quite a lot of gear to achieve the desired torque and low speed required. Lego Technic were perfect for this application.
+
+
+#Hardware part:
+
+1x Microchip controller DSPic30f2010. (With minimum parts, no crystal and no power filtering.)
+1x DC Motor 5v 20RPM (GA12-N20)
+1x L293D Push-Pull Four-Channel Motor Driver IC
+1x Optical Encoder Correlation photoelectric sensor
+
+For an example of the used hardware, please watch: https://www.youtube.com/watch?v=1PTPRkB5JZo
+
+#Source code:
+
+Under files you will find the source code to be compiled with MPLAB IDE. The code is written in C.
+
 InitializeTimer1() Sets the timer given the gear ratio of the setup.
 InitializeIO() Sets the Inputs and Outputs

+
+#Usage:
+
 A button allows to change modes between: Stop, Sync Forward, Fast Forward, Sync Reward and Fast Reward.
-
 An optional LED show the actual mode.
