37 Sensors Summary

“37 Sensors” is the common name for a number of kits of small electronic modules. Not all of the kits have 37 modules in them – some have more, some less. Also, although a large number of these modules are what would be considered “sensors”, some are certainly not sensors (things like RGB LEDs and relays).

If you are curious as to how to interface to these common modules, this site has interface information and example code for more than 37 of these modules. If you have questions or more information to share, please comment on the module page. If you have created a project using a certain module, it would be nice to hear about that, too!
