I was playing with some EEPROM chips I ordered when I had the idea to add an indicator LED to the I2C bus much like the TX/RX LEDs on the Arduino board. The problem is I have absolutely no idea how I would accomplish this.
I'm looking at the 2 analog pins on the Arduino that I'm using for this and I'm baffled. Any tips or best-practices on doing something like this
without disrupting the circuit would be amazing.
Thanks in advance
EDIT: I probably shouldn't have said "without disrupting the circuit" as it comes off a bit ambiguous. "While keeping everything working" might have been a better choice of words.
