BlinkM-controlled by iPhone via BLE and BlinkM with Xbee
/Twitter user Yoshimune KITTA made two cool BlinkM hacks, complete with pictures and code. It's really cool to see how small the code can be, thanks to powerful libraries.
The first is a Bluetooth 4.0 Low Energy (BLE)-controlled BlinkM. Control BlinkM from your iPhone! The code gist: BLE Shield + BlinkM gist
The second is an Xbee-controlled BlinkM. The code gist: XbeeBlinkM
Thanks @epic_yoshimax!
