littleBits Projects: Remote Control Anything With Wireless Modules

This is part of an on-going series of posts about littleBits projects. littleBits is available in the Adafruit store – Starter Kit, Extended Kit, Base Kit, Deluxe Kit, and Synth Kit.

Feel like you need a little space? Gather up your favorite littleBits inputs and outputs, connect ‘em to the wireless receiver and wireless transmitter and your world of [project] possibilities opens waaay up – up to one hundred feet! Never before have two little modules had such a huge impact on your inventions.

The combination of the wireless transmitter and wireless receiver acts as a very long wire module (without the wire!). A signal that passes through the wireless transmitter on one circuit and comes out though the wireless receiver on a second circuit. So, to enable wireless capabilities, you always need two circuits – one to send signals and the other to receive them. For those who are interested in how the signal is transmitted via 2.4GHz radiowave, check out this link.

Check out the following awesome projects made using the wireless modules:

Remote Controlled Parachute Deployer

This parachute bag opens when its servo is triggered by littleBits wireless modules. Throw the parachute bag from a high place (be careful!) and with the push of a button, deploy the parachute in midair. Go from freefall to floating wirelessly!


Remote Control Facetime Car

Using a pair of wireless modules, a couple DC motors, a servo, and 2 smartphones, you can explore the unknown — like Mars or under the couch! Here is a solution for a future astronaut or a person desperate for a quarter. Set up a videocall between two smartphones and place one on the vehicle and one in the controller. Slide dimmers on the controller to steer the vehicle and control the gripper arm. Drive your vehicle wherever you like and feel like you are riding along.


Wireless Doorbell Synthesizer

Turn your doorbell into an interactive wireless instrument! Let guests play a tune on the keyboard from the outside, wirelessly transmitting signals to the inside, where you are able to modify the sound from the speaker using oscillators and an envelope. This combination of synth and wireless modules adds a whole new level of fun to ringing a doorbell.
