I have one of these and was wondering if anyone is using it with I2C.  I would like to add a 20x4 I2C LCD screen, but wanted to see if it would work.

Thanks

If you want to display the data on an I2C LCD screen then just use the Wire library. On the UNO connect A4(SDA) A5(SCL)
add to code:


#include <Wire.h>

void setup ()
{
Wire.begin
}
void loop ()
{
Wire.beginTransmission(device address)
Wire.write(incoming_char)
}
