The code and schematic file for a RGB LED chaser I built using an Arduino Uno. There are ten multicolored lights that turn on and off with five different effects. Pressing a button changes the effect.

In our circuit we are going to use CA (Common Anode or Common Positive) type. In Common Anode type, if we want RED LED to be ON in, we need to ground the RED LED pin and power the common positive. The ...

For connecting 5 RGB LEDs to Arduino we need 5x4= 20 PINS usually, by we are going to reduce this PIN usage to 8 by connecting RGB LEDs in parallel and by using a technique called multiplexing.

Please note that for johnny - five project require "standrart-firmata" or "standrart firmata plus" program. This program must be loaded to arduino memory before you can run NodejS with johnny-five ...

Here, D11-D10-D9 pins of Arduino is used to drive the Red, Green, Blue Anodes of the common-cathode RGB LED (L1) through independent 270 Ohm current limiting resistors (R1-R3). Common cathode of the ...

RGB LED Cube Circuit Diagram. The circuit diagram of RGB LED CUBE is shown in fig:7. We have 64 LEDs in this cube and need to control each color and each led individually. So for that, we need 64*3 ...

The second LED pixel grabs RGB bit sequence, displays it, and so on, until the end of the chain is reached. The PWM pulses are varied to produce multiple colours with the combination of RGB LEDs.
