USB HID Keyboard Device for Interactive Applications

It turns out that with very few components and some freely available firmware you can put together a USB Human Interface Device. The HID device examples linked to below register themselves as keyboards. The aim of this project is to bread board a device with a temperature sensor. Update the firmware to read the temperature sensor and write out the value via the keyboard interface and finally provide the sensor data via a web service.

Inspiration

• Easy Logger
• Caps Locker

Tools

• AVR Microcontrollers

Outcomes

1. USB device on breadboard
2. Firmware that reads from temperature sensor and writes out via HID interface
3. Web service to make temperature available
