Well, its progressing! After a battle with the display, I now have it running on breadboard with the DHT22, showing the Ambient conditions,

I wonder though if you could clarify something for me please Chris? I also have the DS18 connected, but not yet the MOSFET driver and heater. Should I be seeing readings from the DS18? At what point in the build should I be seeing data other than the Ambient readings?

I recall seeing someone mention a pushbutton somewhere in the thread, but dont see one in your diagrams?

EDIT - Just found the v.4 update 2 folder, thanks! The test sketches were what I needed - my DS18 looks like its duff! Only reading 0.75V parasitic power at the signal pin! Typical, one of the few items I dont have spares of!

Cheers
