 # Star-Track
+more info: http://www.instructables.com/id/Star-Track-Arduino-Powered-Star-Pointer-and-Tracke/
 Arduino powered GoTo-mount inspired star tracking system.
+There are two Arduino's working in order. Arduino Uno being master and nano being the slave.
+
+Master module
+
+The master(Uno) module has two inputs,
+
+1-Gyro data
+2-RTC(Real Time Clock) data
+
+and 6 outputs,
+
+1-cw(base motor clockwise)
+2-ccw(base motor counter clockwise)
+3-stahp(base motor stop)
+4-cw2(DEC motor clockwise)
+5-ccw2(DEC motor counter clockwise)
+6-stahp2(DEC motor stop)
+The RTC is set to UTC time, a function calculates local sidereal time in degrees and rotates the mount to 0h RA position. The loop constantly checks if the gyro data is equal to the user input & sidereal time data. The default is 0,0. If there is a change and the equality breaks the master module send a command to the slave module.
+
+If the user value is higher than the gyro value a signal is sent through cw the motor turns clockwise.
+If the user value is less than the gyro value a signal is sent through ccw the motor turns counter clockwise
+If the user value is equal to the gyro value a signal is sent through stahp and the motor stops
+same for cw2,ccw2,stahp2.
+
+This way the mount will turn to the user-specified coordinates. And update with sidereal time thus it will track the sky.
+
+Note: I could use serial communication between the two Arduino's but since the analog pins are used by the inputs I had to use digital pins.
