Re: Cannot connect to DS18B20 from console

ok... I solved it...

There's a difference between a 4.7K and a 4.7M resistor... :oops:

Sense Hat Rubbish temperature accuracy

I've just got my Sense HAT after waiting about 2 months for it to be delivered from china and am VERY disappointing with the temperature accuracy. I think that it is probably reading temperature at around 10 degrees too high.

I am very new to linux so pretty green when it comes to this technology.

The only thing that I can do is turn it off and back on again but when it starts up there is no way of telling what caused it to freeze. What can I...
