Create a remote control littleBits rover using the littleBits wireless transmitter (w12) Bit ($40) and the wireless receiver (w11) Bit ($40). These wireless bits can also be found in some of the littleBits kits, (for example the Gizmo and Gadgets kit).
The wireless modules can pass up to 3 signals. Depending on what you are trying to remotely control you could mix and match between dimmers, buttons and toggle switches. If you add some littleBits proto modules you could come up with some interesting designs.
Step 1 : Build the Remote
To create the wireless remote for the a Rover we needed to control the left and right motors , for this we used the following components:
- 1- littleBits mounting plate (comes with base set)
- 1 – littleBits fork module ($12)
- 2 – littleBits dimmer($8) or slide switches ($10)
- 1 – littleBits wireless transmitter
- 1- littleBits power module with battery ($6)
We connected the power module to a fork module and then the fork module powered our dimmer modules. We mounted all the components on a littleBits mounting plate, and we taped the battery to the back.
The littleBits motor circuit is quite simple, the only important thing is to ensure that you have the wheels turning in the same direction.
