What is this video series about? I'm building a robot gripper arm from scratch! Follow me on my journey as I make a breakthrough, hit a wall, and even check out what parts I'm using! br br The Raspberry Pi robotics project I've been working on is coming to life nicely! In today's episode I showcase hooking up a couple Elegoo stepper motors and ULN2003 driver boards while discussing some of the stumbling blocks and lessons learned along the way. If you're new to robotics but like building things from scratch this video is for you! br br SUPPORTING CHALLENGEYOURSELF.BLOG br If you'd like to support my work please head over to and become a patron today! br br FOLLOW CHALLENGEYOURSELF.
