Hi. i`m planning to connect 2 arduino minis. On one end i need 3.3v 8mhz version to avoid level shifter for the display, On the second end i think i need 5V 16mhz version (~4meters away) i need 5V option as i have 5x pressure sensors with range 0.5v-4.5v.(unless i can supply 5V signal to 3.3v arduino version)
Is it possible to get them talking together?? I2C will work??
thanks in advance
