You can control your Bits wirelessly with the inseparable wireless receiver & wireless transmitter pair. The wireless transmitter gathers and encodes information (such as where you want an RC car to move) to send to the receiver. Pair this Bit with the wireless receiver, and you’ve got a remote control for your Bits.
This update on the w12 wireless transmitter allows for multiple wireless inventions in the same space, making it ideal for schools and makerspaces. The wireless Bits are able to communicate on 5 transmission channels, like a walkie-talkie. They just need to be set to the same channel (labeled a, b, c, d, and e) in order to talk to each other.
A single transmitter can send its signal to multiple receivers on the same transmission channel. However, multiple transmitters can’t send their signal to the same receiver. The 5 transmission channels allow for up to 5 transmitter/receiver pairs to be used in the same vicinity, which can reach a distance of 100 feet indoors!
