Hi there guys
I am a total noob to electronics and C programming, in desperate need of some help with an LDR Laser trip alarm. What I've managed to do is get the LEDs or Buzzers to blink when there is no light on the LDR, And I have a master switch to toggle the whole system on or off.
However, this is an installation piece and I'll be setting up a perimeter of beams, not just one beam bended all around but four beams as i would like to have four corresponding buttons to disarm the blinking buzzers or LEDs and the LDRs should then start searching for activity again after a brief amount of time...
This is an exam piece, so your help will be greatly appreciated. Thanks a lot.
Here is my code so far... http://dl.dropbox.com/u/60078359/LDR_Alarm_Master_Switch.ino
