The 4794 LED Driver example

Hi there,

I am new to Arduino, and I am also trying to complete this example.

I have the circuit breadboarded, but the circuit simply will not work.

The circuit is complete, except for what I am assuming are diodes (?) between the current and the LEDs.

Are these crucial to the circuits operation?

The TX light also blinks, and I'm not sure what that means exactly.

I have posted photos here:

Any help would be greatly appreciated,

Thanks
