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 ...

//This program is designed to control a switch and LED using PWM. The program debounces a switch to ensure that only one press activates power (on/off) for the LED. The program is set up in a way that ...

I have spent at least an hour almost every day since the 80’s advancing my knowledge in electronics. Recently I brushed up my knowledge on LED fading secrets and attained something pleasant. Now, I’d ...

Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using the ...

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 ...
