Updated and slightly improved version of my DC motor servo driver software. Originally programmed to run on an arduino nano and drive an N20 gearmotor with encoder to make an ultralight 3D printer ...

An Arduino Nano is the heart of the build, ... The servos, one per key, are ... The brains of this operation is an Arduino Nano, with an A4988 stepper motor driver controlling a NEMA17.

The 32U4 in arduino-land can sometimes be a bit problematic with regards to firmware updating and reset issues, “brickable” as it were. The Nano footprint is quite nice (similar in size to a ...

In terms of the hardware, this robot uses an Arduino Nano as the brain, two motor drivers to control the DC motors, a wireless transceiver module to receive signals from the transmitter device ...

Thanks to the inclusion of an Arduino Nano Servo shield and EasyVR3 Voice recognition module. Watch this video on YouTube. “My build is loosely based on a Robot by DIY(makers) ...
