Serial randomness!

Alex,

When you do something like PORTB = 8, it sets all the pins in PORTB.

Since PORTB.2 is the A/D's Chip Select pin, every time you turn on an LED or Relay, you are also Enabling the A/D converter. Probably getting it confused.

And that chip can be clocked at up to 1 Mhz.
6 seconds is an awful long time to read 8 bits.

Hey Darrel,

Thank you loads for your response! I'm currently away from home and so unable to test your theory, but i'm convinced that will be the cause of the issue! I'll keep you updated as to when I can test it and thanks to everyone who helped.

Cheers,
Alex
