Hi all, Im using 2 arduino (nano's) and 1 LCD on a I2C bus. The master arduino sends data to the slave (which doesnt send anything back, or acknowledge, it just listens on the I2C), and the master controls the display. Both arduino's are powered separately via USB. I simply put the SDA, SCL and gro…
