in Aquarium, Raspberry pi

Raspberry Pi tweet temperature

 

I wrote a small python script to tweet my aquariums temperature so that i can monitor it as I raise the temperature slowly to 86°F to fight an ich outbreak 🙁 .

Updated the code, had to add the temperature tuple in a new variable using srt(temp). Code is now working and running on my Raspberry pi.
