We’ve featured loads of IR Arduino projects and they are all exciting and unique. The projects spring from a specific need or problem where a custom infrared remote control is the solution. [… ...

To make that actually work, Robofun paired an Arduino board with some capacitive controllers for the base, and connected that to a Raspberry Pi that linked the keyboard to the TV.

The Gesture Keyboard is a device that translates gestures into letters. It’s made by an Arduino Pro Micro, an HC-06 module for Bluetooth communication, and an MPU-6050 accelerometer.

Technical Details and Components The keyboard was built using an Arduino board together with a fuel capacity of controllers, which is then connected to a Raspberry Pi mini computer.

The Arduino uses a shift register to interact with the keyboard’s 8×10 matrix, and the sketch translates any serial data it receives into the keypresses the clone is expecting.

Amazon is currently offering the Verizon Moto G for just $70 with no contract. It won't work with Verizon post-paid plans, but you can get it on the ...

Microduino: An Arduino clone nearly as small as a quarter, for $20 Arduino Uno capabilities divided into two small boards for extreme portability.

Taliyah Huang's Mouseky keyboard can also replicate most of the MacBook's trackpad's functionality.
