Relay Accessory Kit

Workshop 12 provides automated control of a 8-channel relay board allowing you to control various different electrical circuits within your vehicle.  Whether this be accessory lighting, suspension, fans, etc. you’re able to use a clean installation in your dashboard by using the Brainiac Switches app.

Our kit is made up of off the shelf parts and an upcoming plastic housing to hold everything in a protected unit.  This makes it very simple to source the parts you need to create your install.

So What Do I Need?

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 Ardunio 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.


The last part that you’ll require is the Workshop 12 plastic housing to create a secure enclosure for the two boards and the jumpers.  Currently this housing is under development and when completed will be made available in our Shapeways store front.  We’ll be providing a full tutorial video on how to configure the relay module and assemble everything once the enclosure is completed.

For now you can check out the video below that walks you through what Arduino is, how it can control relay boards and the general concepts of Maker fun 🙂
