Attempt to build a independent LCD Node Sniffer / Scanner
For easy debugging of just for fun ... (Still in progress)
If there's animo let me know (before I put time into the fritzing)
This is how I connected the LCD true a PCA8574 I/O expander chip to the Arduino
using the I2C bus (A4 & A5).
If having trouble I made a little sketch for searching for adressen on the i2C bus
The heart of the project ... the code
It's not finished at all, but feel free to comment me and make / share changes to it.
----> v 1.1 <---- Keep an eye on this number for updates.
