Once again software programmer and technology enthusiast Nick Fryer has shared another useful project with us - a remote-control for a PC in order to control reading software. The system uses a Freetronics Eleven at the user's end with two large buttons for "forward" and "backwards". When the buttons are pressed a character is sent via 433 MHz wireless to a receiver with an Arduino Leonardo - which can simply emulate a USB keyboard and thus control the software for the reader. It's a great solution and makes life easier for the user.
If you're making your own Arduino-based project that needs USB emulation - check out our LeoStick. It's the Arduino Leonardo-compatible board that's cheaper and smaller than the original:
Apart from being one of the smallest Arduino-compatibles on the market with USB, it also has an onboard RGB LED and piezo which can be used a knock sensor and various tune and sound effects. Plus you can add extra circuitry with the matching protostick! For more information and to order, click here.
