Smooth Moving Micro Robot Arm

Talk about cheap stepping motors and there's a good chance someone will mention the 28BYJ-48. Or maybe he or she will not remember the part number and say something along the lines of "That 3 dollar stepper used in air conditioners! You know! B28 something!" Truth be told, it doesn't get much cheaper than 3 dollars. The 28BYJ-48 is the queen of ultra-low-cost steppers.

But is there good in the cheap? Can this 3 dollar stepper motor achieve greatness against all odds? No. But hey, it's only 3 bucks, so you might as well get a dozen and see what you can come up with. I decided to throw the steppers at a simple robot arm project.

Buy the 12V 28BYJ-48 stepper motors used in this project on Amazon (Affiliated link):
