EEPROM example for PIC1814K50

For a previous project involving stepper motors, I wanted the microcontroller to remember exactly where the stepper motor was even after power loss. There wasn’t enough time to attempt it then, so I thought I’d try something similar now.

Second attempt at making an x-y plotter (TinyPlotter)

This plotter was built using parts from cd disc drives. The parts that actually control the motion are the steppers in the cd drives. The steppers are normally used to move a laser diode back and forth over the disc … Continue reading
