Their sensor uses a four-lead RGB LED, but we suppose ... bouncing back from an object as an Arduino drives the LED through all possible colors with PWM signals. The sensor needs to be white ...

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 ...

Yep, RGB LED Christmas Lights with PWM for under $7. Can’t beat that. [James] wrote an Arduino library to control these strings and put it up on Github. While your local Walgreens has probably ...

Applying PWM switching to the LED outputs can be particularly troublesome with regards to EMI. To optimize EMI performance, the IS31FL3248 includes a programmable spread spectrum function to lower ...

The Aurora fans from In Win are spectacular to look at, and the additional RGB LED strips takes the amount of lighting over the top! The 3-pack kits are affordable with dual options of control ...
