For April, we are raffling off a protoboard with a temperature, humidity, barometric pressure, and light sensor on board, with a RJ-45 connector for running a patch cord back to your arduino. Put this board in a clear vented project box outdoors and be a Citizen Scientist!
All participants will be sent code, full schematics and connection instructions.
Tickets are $5
