The program also has an internal timer to approximately 3 minutes between the microcontroller in sleep mode in which consumption will be minimal, to save the battery. And it will reactivate the program until you press the button, starting over allowing timing and take readings we require. 268 src="/file/tech2/circuit/2010/0203/ET35303201007231157293201106091208388708.jpg" width=550 border=0>

The program is also complimented inizialización a function which shows the blinking leds, to argue that this in active process and that at the end of this sequence we can take appropriate measures.
The bulk of the program is effected by a loop of reading and comparing the reading which collects and compares GP1 activating the corresponding output.
In order to function alone is sufficient to connect the ground wire to any metal part of the chassis or failing to ground.
the code is open and available to anyone who
want, just send an e-mail and ask.
