ここでは、アナログ信号を扱う方法を学びます。Arduinoを使うと、アナログ信号を読み取ったり、それをもとにLEDの明るさを調整したりできます。この章では、可変抵抗を使ってLEDの明るさを変えるプログラムを作ります。 アナログ信号とデジタル信号 ...

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 ...
