The wireless receiver receives a signal from your wireless transmitter and activates your littleBits circuit remotely! The three channels (labeled 1, 2, and 3) on the transmitter a nd receiver correspond to each other and can be used simultaneously. The bit can receive a signal at a distance of about 100 feet indoors. Multiple wireless receivers can be used with a single wireless transmitter, but only one wireless transmitter can be used in proximity to another wireless transmitter. Check out our Tips + Tricks for more ideas on using the wireless receiver. New! Updated wireless bits, with 5 channel functionality, are available in the Gizmos and Gadgets Kit. Show more
