I am trying to make a project with the smallest project controller (an Arduino Uno would be overkill). I was planning to use an ATtiny85, but was not sure whether I would be able to properly communicate between a 7 segment serial display using Serial UART or I2C. Does anyone know whether either of those would work or have any experience doing so?
I have reviewed Sparkfuns tutorial, but since not all functions that work on an Arduino work on an ATtiny85 I wasn't sure whether this project would work
