How to run two CNC shields (other one as clone) with one Arduino UNO
I learned a nice thing about Arduino CNC shield today. I have a project coming up where I need 3 axes. On each axis, there will be 2 motors (cloned, running in sync). That means I need a total of 6 motors and drives, but CNC shield only supports 4 drives (axes). So I needed

How to use H-bridge HG7881 (HG7881CP) module with external power supply and Arduino UNO
First-time use of H-bridge HG7881 (HG7881CP) module was pretty confusing for me. I didn’t find good (if any?) information about wiring this module up and running it with Arduino. But same time it seems to be quite popular. Here I share how I connected it to an external 12V power supply. You can use any other voltage
