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 ...

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 ...

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 ...

Pulse Width Modulation is used to vary the pulse-train width. Applications of PWM are speed controllers, limiting power of motors and LEDs. It is a square wave with a varying high and low time. Terms ...

In exploring the use of analogWrite() and digitalWrite() on the Raspberry Pi Pico using Arduino, I have discovered some strange behaviors when switching between those modes on the same GPIO pin. This ...

If you are interested in building robots, then it is certain that you need to learn how to control the speed and direction of a DC motor, and in one of our previous tutorials, we did just that using ...

Arguably, the ATmega328P is being left behind as ‘the Arduino processor’ because Arduino’s are following the rest of the world and going 32bit.
