Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

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 ...

When multiple PWM converters are connected in series (or in parallel) in a power electronics circuit, it is appropriate to run all converters at the same frequency but with certain phase shift among ...

After a major water leak flooded my home, I realized alerts alone weren’t sufficient—I needed automatic shutoff. This project combines a hacked Gröhe Guard system, an Arduino Nano, an ESP32, and the ...

Having advocated Arduinos for prototype PWM signal generation, I have just discovered a subtlety that might trip up the unwary (amongst which I count myself). The original idea was not to use Arduino ...
