split flap clock 10-3-2021 auto home test

Auto home using endstop

I'm able to control the motor using only 2 pins by sending the signals that need to go to the uln2003 through a 74hc139 (demux/decoder) and inverting the output (I'm doing this using a NAND gate because I didn't have any inverters).

at 0:15 I press the reset on the Arduino, after which it will look for the home position. After finding the home position it will continue counting.

This is basically just a test, the final idea will be to make a clock out of this.

Everything is 3d printed in ABS plastic
