Internet of Things Chess board - Development of RFID chess piece detection running on the newest generation AVR microcontrollers.

When radio frequency identification (RFID) was first introduced, it was predicted to changethe world, much like the Internet of Things (IoT) has been these last few years. Even thoughthe adoption of RFID was slower than it was predicted to be, much like IoT can seem to be,the industry is continuously finding new ways to uses the two technologies. By designing a chessboard that use both technologies we have shown a way to put RFIDon the IoT network. A minimal BOM RFID solution is presented, compatible with theEM4100 protocol, running on 125 kHz. The approach of using RFID to detect pieces on a board can be implemented in all gamesthat have a similar form-factor, such as scrabble, monopoly, checkers. In fact, any flatsurface that has defined areas of interest can take use of this implementation.
