Lumenati Alien Garden
Dia 
Hardware Hookup
Before you can begin building the garden, you'll want to wire and solder all the boards. Measure how far apart you want all the plants to be and cut wire lengths accordingly.
Start by connecting your first Lumenati board to the SparkFun Redboard or whichever microcontroller you've chosen. Wire the first board as shown in the table below. There are two sets of 5V and GND pins; make sure that you leave one set open to make the next step easy!
| RedBoard | First Lumenati Board |
|---|---|
| GND | GND |
| 5V | 5V |
| 13 | CI |
| 11 | DI |
Next, connect your first and second Lumenati boards. You want to connect CO on the first board to CI on the second, and DO to DI. Use the second set of 5V and GND pins on the first board to connect to the second board. Once again, leave one set of 5V and GND open on the newest board!
| First Lumenati Board | Second Lumenati Board |
|---|---|
| GND | GND |
| 5V | 5V |
| CO | CI |
| DO | DI |
Repeat this process from the second board to the third. If you have more plants, you can continue adding boards this way. Ensure you have a power supply that can supply enough current if you decide to add more boards!
| Second Lumenati Board | Third Lumenati Board |
|---|---|
| GND | GND |
| 5V | 5V |
| CO | CI |
| DO | DI |
Once the wiring is complete, it's a good idea to upload code to the RedBoard and test everything out before installing into the garden. See the next section for the code.
