It has all the required voltages (3.3V, 5V, 12V). Since I didn't want to use batteries or multiple DC adapters for different voltages, I transformed my old ATX PSU to a DIY lab power supply unit. I read that I should not use the 5V pin on Arduino because the Due based on 3.3V. The program is working (basic SerialPort buffer writing with C#), everything looks good, but I'm afraid I'll fry something because of the different voltages. I'd like to control the stepper motor and the servo via USB. A chunk of jumper cable, a breadboard, lots of free time and big plans.An old ATX PSU (Enermax Liberty ELT500AWT 500W).An Easy Driver stepper motor driver (v4.2).A biploar stepper motor from a DVD driver.This is my "Hello World" project, I have: I tried to do my best to share my thoughts and ask the correct questions, but I'm sure I made some huge mistakes, please excuse me.
Hi all, this is my first post here, and my second day with Arduino and with electronics, so I'm really a beginner, also not a native english speaker (let me know if something doesn't make any sense).
