Charlieplexing is a technique of controlling many LEDs using a few I/O pins. Charlieplexing is same as multiplexing, but it uses the tri-state logic (high, low input) to reduce the number of pins ...

The real-life closeup image of a WS2812B LED is given below. You can see that the WS2812B die is connected to 3 individual LEDs namely Red, Green and Blue using gold wires. The video below shows the ...

This NeoPixel LED lighting based on WS2811 driver and Arduino digitally produces red, green, and blue (RGB) lights and the combinations. Originally introduced by Adafruit, the LED strips come with ...

Here is a 3D light show that will astound you with its combinations. Inexpensive and easy to make thanks to an Arduino controller, the design enables you to play with the existing effects and, most ...

Perhaps one of the most common modules in an Arduino starter kit, the RGB LED lets you create all sorts of colors with just four pins from the Arduino. This tutorial demonstrates two ways to use this ...

マイコンボードを使ってシンセサイザーを作っているのですが、私が使っているArduinoのボードは入出力PINが少なすぎます！ ボタンだけで46個、LEDは50個。。多いな。 最初から心配でした 電子工作を始める動機は今までソフトウェアで作っていた楽器を実機 ...

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 ...

I made this Arduino 8 bit binary led counter as a solution for one member from Arduino forum. He asked if somebody can make a project that displays a decimal number in 8 bit binary format using 8 leds ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led – the green one on the left in the photo. And it has a pair of yellow leds – called TX ...

Its not possible to control the RGB led on this board with the neopixelWrite() function since the PIN number is wrong in the pins_arduino.h Not sure if the macro or the LED_BUILTIN constant should be ...
