# With this code, a CloudBit and a pressure sensor from littleBits you are 
# able to build your own TMI machine. Place the TMI machine with the presure sensor 
# on the toilet seat. This will enable the machine to send a tweet about when and 
# how long the visit at the loo was. See examle at https://twitter.com/tmimachine
