DIY 2 motorised axis equatorial mount ( RA & DEC) with GOTO remote.
project based on an ARDUINO UNO + SD card shield + 2 POLOLU A4988 . DC current out of a 12V Lipo battery .
wire remote control is I2C protocol remote built with I2C Joystick + I2C LCD screen + I2C matrix keypad.

don't hesitate if any question but be careful i'll not give any 3D design and nore arduino programm . this video is just information of what can be done with a simple UNO.

hope you'll enjoy

Just confirming, the project was made by you right?

yes , completely .
mechanical structure is based on equatorial wedge + 2 skywatcher dovetail L-bracket with worm wheel on which i've fixed the NEMA 17 stepper with aluminium sqaure.
nevralgic part of the project is the electronic module: Arduino + SD card shiel + Pololu drivers and for sure the ARDUINO program.
SD card is used to store the NGC object file with coordinates of the NGC objects. it is used in option C for GOTO positionning.
