Need help making a timer
(programming.dev)
Hi there. When I've needed to use these displays, I needed to save pins on my MCU, so I used the TM1637, which can drive up to 4 digits using only 2 pins, though it isn't i2c.
Otherwise, you'll need to build a fat function, with two inputs: updateDigit(digitPosition0-3,number0-9)
Edit: here's a quick tutorial: https://www.makerguides.com/tm1637-arduino-tutorial/
Arduino is an open-source electronic prototyping platform enabling users to create interactive electronic objects.
