Adafruit Learn Guide

A word clock which uses NeoPixel RGB LEDs for a color shifting effect.

Hardware

• Trinket Pro 5V (should work with other Arduino-compatibles with minor modifications)
• DS1307 RTC breakout
• NeoPixel NeoMatrix 8x8
• laser cut faceplate & enclosure

Software

This code requires the following libraries:

• RTClib
• DST_RTC
• Adafruit_GFX
• Adafruit_NeoPixel
• Adafruit_NeoMatrix

Wiring

• Solder DS1307 breakout to Trinket Pro, A2 to GND, A3 to PWR, A4 to SDA, A5 to SCL
  If you leave off / clip the unused SQW pin on the RTC breakout, the breakout can sit right on top of the Trinket Pro for a compact design! It'll be difficult to reach the Trinket Pro reset button, but you can activate the bootloader by plugging in the USB.
• Solder NeoMatrix 5V to Trinket 5V, GND to GND, DIN to Trinket Pro pin 8.
