For the second program I made the same Config changes, the program worked a treat two:
When the pot is turned LED D3 lights at approx:1.25V (pin13), D2 lights at 2.5V (D3 goes out). At 3.75V D1 lights (D2 goes out). And at 4.95V D0 lights up and D1 goes out.
I must say mackrackit, this is very clever stuff.
I'm thinking for the project, the LDR set against a pre-defined ADC voltage trigger level would be spot on to send the data at a set light night time light level.
I'm still doing loads of reading / studying, I've got a few things I'm not sure of so may have to get back to you on those, bear with me.
