Help with code error - Error compiling for board Arduino Uno

Projects Programming
1

Hello all,

I am trying to build a 'simple' word clock but I'm already stuck at the copy/paste of the code from the adafruit tutorial. I copied over all the libraries as per the instructions on the tutorial and I also included an additional library "#include <U8glib.h>" as per a youtube video with a supposed solutions but it didn't work.

The error appears when I try to compile or upload the code to an Arduino Uno.

I am a beginner, I've done other projects but I've never encountered this type of errors. I've attached screenshots of the Arduino Library and the "Adafruit_GFX_Library" as per the error description.

Please could someone kindly help!!

Thank you so much!
Henry

WORD CLOCK - 8x8 NeoPixel Desktop Edition
by Andy Doro

A word clock using NeoPixel RGB LEDs for a color shift effect.

Hardware:

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

Software:

This code requires the following libraries:

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.

did you install all the libraries? looks like you're missing an I2C library
