Hallo again,

10k's and clock now at 3.3v but the IC only works at 5v.

Got a bit carried away before - my friend George, who's the sensor
co-explorer, is normally only available on Friday's so very much had that
Friday feeling - and of course giddy with the sensors all finally working.
Started to lose the plot with it all last weekend and was getting a bit
frenzied with my interactions on the breadboard - was probably the wise
thing to just put it down for a few days and come back with a clear head.

Think my codes still a bit buggy as I'm only getting one sensor coming into
Pd but have 2 sets from the console.

Back to it,

Julian
