First you'll need our supported 8-channel relay board. This board will support a 10A load and also has small LEDs on each of the relays to know which relays are in the ON position.

The 5v power to run the relays is provided by one of the pins going to the Arduino UNO. The board itself also requires a 5v power supply.

You can find the LC-202 sold at a few different places, but we've provided a link below for full details.

 

 

 

 

Next you'll need to acquire an Arduino UNO. The Arduino provides the brains for the relay board and is connected to the tablet and Brainiac Launcher via the USB port.

The script that needs to be loaded onto the Arduino will be provided by Workshop 12 along with instructions on how to load and configure the relay accessory kit.

Depending on how your wiring is configured you can either power the Arduino by a powered USB hub, or use the direct power jack to wire it into your electrical harness. The Arduino UNO can be picked up anywhere, but we've provided a link below for quick reference.

 

 

To connect the relay board to the Arduino you will require some Female/Male jumper cables.

These simply bridge from the Arduino's female control ports to the male pin connectors on the relay board.

These can be picked up anywhere, but we've provided a link below for reference.

 

 

 

Take a look how the Arduino and Relay Board come together to create a connected experience with the Brainiac software.

Trigger relays on a momentary switch by tapping, and latch the relay on a long press of the assigned button.
