I've updated the sketch and schematic to fix mislabeled SDA & SCL pins.

Try using MatrixClock-jan-2018.zip from the Code section, I updated the sketch for v1.8.3 a while ago, it should deal with the progmem changes
Last year I updated the github Chromaduino code in a number of ways, including correcting the non-standard I2C address. But the clock zip file here on Hackster is the original from 2016.
I suspect that's you problem. Try changing the
#define LEDS_I2C_ADDR 0x05
line in LEDS.cpp to
#define LEDS_I2C_ADDR 0x70
If that doesn't work, perhaps start by trying the ChromaduinoMaster.ino sample sketch on github, see if that works.
