First test: Spindle RPM control with potentiometer + Arduino + LinuxCNC ⚙️ #linuxcnc #arduino

This is our first test controlling the spindle RPM on my CNC using a potentiometer connected to an Arduino Nano. The Arduino reads the analog input and sends the value directly to LinuxCNC, which adjusts the spindle speed in real time. 🚀

Setup:

Arduino Nano

Analog potentiometer (A0 input)

Spindle speed control via LinuxCNC
