Before I learned about the Spark Core Kickstarter campaign, I was playing around with Arduino and a nRF24L01+ mesh network. Once I learned about the Spark Core, I basically dropped everything I was working on. Finally a cheap, powerful, wi-fi enabled MCU package! Once I get another Spark or two, I’ll probably try to port over the nRF24L01 stuff and use it as a gateway (instead of a crappy RaspberryPi).
Does anyone else have a stack of Arduinos now collecting dust? Any project ideas for integrating them with the Spark?
