Note: <\/strong>This is an archive of my Year 10 Semester 1 STEM Project (2021). The powerpoint slides have been converted to article form. Everything but a few stock photos (so I can give an updated source) remains unchanged from the original presentation.<\/p>\n\n\n\n

For my Year 10 S1 STEM Project, I wanted to expand upon one of my previous years project: the DIY Arduino using an ATMega328P micro-controller IC, and an array of complementary components to allow it to function as an Arduino. In this project, I set out to design an all-in-one, stepper motor driver board using the ULN2003 stepper motor driver ICs. This IC choice was made because I wanted to be able to control the very inexpensive 28BYJ-48 uni-polar stepper motors with very inexpensive driver ICs.<\/p>\n\n\n\n

I learnt a lot in this project such as circuit reverse engineering, circuit debugging, schematic and PCB design, and it was my first time designing and soldering with SMD components.<\/p>\n\n\n
