I wrote this when I could not find Arduino code online that could accurately and reliably read 25kHz pwm signals. For reliable PWM you must handle the following edge cases: 100% or 0% PWM signal with ...
In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to analogue converter is needed. The machine uses a ‘grbl’ controller, which has an ...
This project is a simple, variable-frequency sine wave generator built on the Arduino platform. It uses Pulse-Width Modulation (PWM) to produce a digital approximation of a sine wave, which is then ...
