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 ...

What Are PWM Pins? The Arduino Mega's PWM pins are digital output pins located on D2 to D13 and D44 to D46, coming to a total of 15.

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 Arduino library for PWM.

The PWM output is set as an external voltage using the “Inputs and Sources” components (remember, the output from the Arduino is the input to the circuit).

Wiring diagram Arduino sketch Now is the right time to make some key design conclusions regarding the power inverter stage. Yes, you can make a power inverter circuit that uses Arduino to generate the ...
