I have the circuit connected as shown in the diagram…. but I found if you don’t connect the ground from the Arduino to the Easy Driver, the motion is really jerky.
I guess I was kinda surprised at how few pins you have to connect. The guide starts out indicating you have to pull RST and SLP HIGH so I was just waiting to find something to go wrong, albeit ground and not the other two pins. Maybe indicate that those two pins are normally HIGH and add the GND connection in the circuit… or maybe I’m just reading too much into it ;/
The SLP function puts the motor to sleep – how do I “pull it low” from my Arduino? I’m guessing that means connect to ground, right?
Was wondering if this drives 5 volt stepper motors?
It depends on the motor. This board can only source 150mA to 750mA/phase to the motor, so that’s the spec you need to really watch for.
the github link next to the code links to the design files and not the code as indicated.
The product repositories contain both the design files and the example code. You’ll want to check in the Firmware directory in the repository for the Arduino sketches. If you download the .zip of the repository, or clone the repository, you’ll get all of the design, firmware, and production files.
Ok, thanks, I didn’t think to check the firmware directory.
