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 ...

Macetech’s ShiftBrite is a high-power RGB LED coupled with an Allegro A6281 backpack. The A6281 uses three 10bit pulse-width modulators to mix millions of colors using the red, green, and blu… ...

He used an Arduino, and multiplexed RGB LEDs with some digital potentiometers to create a color mixing keypad. ... 2 150 ohm resistors; 8 1 kohm resistors; To reliably lock and unlock the door, ...

In a recent post we interfaced a small DMX RGB LED Par Light with an Arduino Uno through a MAX485 module. In this post we will learn how to work with a compact USB to RS-485 Converter Module. This ...

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...

As explained by Arduino to Go, each color band on the resistor corresponds to a number but this can differ depending on the band's placement.It's not complicated, but the sheer number of colors ...
