Connecting

As shown here, Trellis is just an LED/keypad controller. You still need an Arduino or similar to do the work of reading

the keypad data and then signifying when to light LEDs.

Luckily, we wrote a library that handles all the hard work for you, making it all very easy!

Download the Trellis Arduino library from our github repository (https://adafru.it/cZf) by clicking this shiny button

https://adafru.it/cZg

Rename the uncompressed folder Adafruit_Trellis. Check that the Adafruit_Trellis folder contains Adafruit_Trellis.cpp

and Adafruit_Trellis.h, and an examples folder

Place the Adafruit_Trellis library folder your

sketchbookfolder

/libraries/ folder. You may need to create the libraries

subfolder if its your first library. Restart the IDE. You can figure out your

sketchbookfolder

by opening up the

Preferences tab in the Arduino IDE.

Libraries (https://adafru.it/aYM)!

Next we will connect up the PCBs, we soldered solid-core wires from the 5 connection fingers and plug them into an

Arduino. We suggest starting with an Uno since its guaranteed to work

Connect the wires:

5V goes to the 5V power pin on the Arduino

GND goes to and GND ground pin
