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 ...

The wiper of the 10K potentiometer is wired to A0 of Arduino (5V-A0-GND), while anode (A) of the test LED is linked to D5 through a 220Ω-470Ω resistor and cathode (K) to GND. #include ...

[Runtimemicro] has the answer, at least if you are writing PWM code for the Arduino. Their free application lets you set a few parameters, visually see the results, and then generates code for you.
