Just follow the schematic diagram to complete the construction, and use any standard 9VDC Arduino power source to energize the system. Here, for demonstration, three different color LEDs (Red, Green ...

Pulse Width Modulation is definitely the preferred method of dimming an LED with a microcontroller, but we were interested in hearing about a different method called Binary Code Modulation. BCM doe… ...

During Ramp 1 time, the PWM signal's pulse width is incremented for LED 1 and decremented for LED 2. For example, let's have the ramp time equal 2 seconds and consist of 128 up/down steps. Thus ...
