To be eligible for prizes, selected challengers must post at least five updates on the element14 Community and a final ...

I made this Arduino project that allows to turn ON and OFF LEDs using a cheap IR remote control as a preparation for the next big step: disassemble my girlfriend’s chinese LED lamp and replace its ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

As described on the Hackster Profar blog, as features go, the Shield sports a reset switch, power LED, Arduino pin 13 LED, Pi GPIO pin 13 LED, headers for full Arduino pin access, and ICSP header for ...

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 and RX – to indicate traffic on the serial bus. Except, on the Micro ...

To actually power and control the entire circuit, [Martyn] used an Arduino loaded up with a program based LedControl library makes programming the spedometer a snap.

The mod works using a MAX7219 chip and Arduino Uno ATmega328 board, which control the two 8×8 LED matrixes making up the eyes. Each matrix is wired up to the MAX2719 chip–expect a lot of cables ...

The UDOO has the same pins as the Arduino DUE, as well as the DUE's ARM SAM3X processor, which is dedicated to the GPIO pins. Android 4.0.4 or Linux (Ubuntu 11.10) runs on a second processor, a ...
