If you have a Arduino MEGA connect the SCL and SDA pins to 20 and 21.

Do not use Analogue pins 4 and 5.

This is just in case there is anyone else out there wondering why there comms isnĀ“t working when the circuit and software is correct.

There must be another idiot like me??? wasted an hour on that.

The info on this thread is fantastic I would like to thank everyone who posted as it saved me a lot of time.
