Pidor is controlling the state of Level2 on the website, spaceapi and twitter

This documentation is work in progress, sorry about that.

Connectivity
connect the doorlock relay to gpio 7
connect button of doorlock to gpio 11
connect the 433mhz transmitter to pin 2 (gpio 17)


Install

put raspian image on SD card and put into rPi

ssh to pi@<ip address>
if that does not work, edit the SD card and put into etc/rc.local "/etc/init.d/ssh start"
sudo bash   # all is installed under root 
apt-get install php5-curl # for twitter
apt-get install git # for getting this
apt-get install wiringpi # for the buttons and stuff
apt-get install gawk # raspian has mawk by default which lacks time functions

tzselect
