Use Digispark Attiny85 instead pcf8574

Hello! Why do not you use Digispark Attiny85 instead of pcf8574?

PCF8574 is a I2C IO expander, Attiny85 seems to be a micro controller. I don't understand what is your question.

To Attiny85, you can connect analog buttons and flash the microcontroller to transfer the state of the buttons on the i2c bus... Easier than connecting the library pcf8574. I can modify your code to support buttons > Attiny85 > i2c For example: http://www.mauroalfieri.it/elettronica/attiny85-iic-wemos.html

We might have different view of easiness. PCF8574 is cheap and everywhere, I don't fell any difficulty.

However, your are encouraged to do whatever you want to the code. That is the spirit and purpose of open source.
