![]() ![]() The stepstick is an A4988 chip mounted on a small PCB with headers on either side. I also used a couple of LEDs and some 220Ohm resistors Some hookup wire, I used solid Cat5 strands. ![]() Other MaterialsĪn Arduino Uno, but any Arduino compatible should doĪ Stepstick, or compatible stepper driver using a A4988 or DRV8825 So, I got some stepsticks and decided to wire them up to my Arduino. The Adafruit stepper motor shield cant supply 2A,and has trouble with voltages below about 5V, so couldn't properly run my motors (they jittered but didn't smoothly move). The Rated current is the MAXIMUM current the motor will take before bad things happen, and the voltage is the calculated voltage that will give a constant current at the rated current, for the motors resistance (V = I x R, V = 2.0A x 1.4Ohm = 2.8V). So, for Stepper motors, the resistance per phase is a constant. Looking at the specs the problem here was the resistance/current/voltage rating I had acquired some Stepper Motors from Ebay, that didn't work well with the Adafruit Motor Shield. ![]() There's lots of great resources out there about Stepper Motors, how they work and what kinds are available, I'd recommend ![]()
