New page

== CHARLEY BETA! ==

== Clock based On/off system ==

My new system I am going to make is a system that on special times turns light on or off.
I want to use this as some anti-criminal system. So, that when I am on vacation still the lights are on at night or day. So the house doesn't look like a house that is asking for crackers or criminals.

For this system I am of course going to try it with shorter times otherwise I have to wait 8 hours for a lamp to get on or off.

So when I start the code I plan it 1 minute in the future.

I already made a lamp go on and off in [[blog 02]]. so I am going to use that same technique for turning on and of the lamp.

Crontab is more manually
Crontab -e
has to be done to open
and have to put this in to make it work

# mm hh dom mon dow command
19 13 * * * /usr/local/bin/gpio write 3 1
20 13 * * * /usr/local/bin/gpio write 3 0

To read a certain part:
crontab -l |grep -v bin/gpio

For the people who don't understand:
*1 Minute 0-59
*2 Hour 0-23 (0 = midnight)
*3 Day 1-31
*4 Month 1-12
*5 Weekday 0-6 (0 = Sunday)

So the text from my is now saying:
gpio write 3 1 at 13:19
gpio write 3 0 at 13:20

( echo "# mm hh dom mon dow command" ; echo '19 13 * * * /usr/local/bin/gpio write 3 1' ; echo '20 13 * * * /usr/local/bin/gpio write 3 0' ) | crontab

( You can of course also use it as alarm clock, then you only have to change the command to the location of the audio file you want to play.)
