Layman’s RGB LED module is an ultra-simple project realized without any ... equalized in order to match LED performance over the operating range. These ballast resistors are used in the prototype; RR ...

In a recent post we interfaced a small DMX RGB LED Par Light with an Arduino Uno through a MAX485 module ... You can see two 4.7KΩ resistors on the A&B differential lines on the module. These bias ...

[Steve] from Hackshed did just this: he integrated an Arduino based webserver into a new network controllable RGB lamp. What makes this lamp unique is that the RGB LED bar comes from an old Epson ...

It uses a 4d-micro-USB module from Dontronics to interface serially and provide power to a Picaxe 08M. The PIC can control color and brightness of a RGB LED. The feedback is given by seven colors ...

It may look a little shoddy, but what’s amazing is that this very functional 3-D interface was built by a hobbyist with parts most DIYers can find in their couch cushions—six resistors ...
