Help in trying to build microcontroller powered Chess Board

Click For Summary
SUMMARY

The discussion centers on building an Arduino-powered chess board that utilizes magnets and reed switches for piece detection. The user encountered issues with neodymium magnets, which generated interference by affecting adjacent reed switches. Alternatives suggested include using less powerful magnets or exploring RFID tags for piece detection. The user seeks recommendations for resources to learn about RFID applications in this context.

PREREQUISITES
  • Understanding of Arduino programming and hardware integration
  • Knowledge of reed switch functionality and magnetic field detection
  • Familiarity with neodymium magnets and their properties
  • Basic concepts of RFID technology and its applications
NEXT STEPS
  • Research alternative magnet types suitable for reed switch applications
  • Explore RFID tag technology and its implementation in object detection
  • Learn about Arduino libraries for interfacing with RFID modules
  • Investigate circuit design for integrating reed switches and magnets in a chess board
USEFUL FOR

Electronics hobbyists, Arduino developers, and anyone interested in creating interactive game boards or learning about magnetic sensing technologies.

Hello all, as the title states I'm trying to build an arduino powered chess board. The chess pieces will have magnets on the bottom and each square of the board will be equipped with a reed switch for detecting the presence of the magnetic field produced by the magnet. I recently tried this out and the neodymium magnets I bought were so powerful the field cut into adjacent squares' reed switches and gave false signals.

Does any know of a less powerful type of magnet that I can use? If you think this would be more of an application of RFID tags (an application that I've seen on the interwebs quite a lot) what sort of resources do you recommend so I may learn how to apply it?
