Tsja
Dombo hier
Een hele dag druk om een turtiol aan de gang te krijgen.
Maar helaas..
Ik zoek dus eigenlijk een te simpele oplossing.
pir 1 ene kant van het bed.
pir 2 ander kant van het bed.
Bed uit led onder de rand van het bed aan voor x minuten.. en dan auto off
Veel sketches geprobeerd maar loop tegen de zelfde problemen aan.
Lijkt wel of de pir anders werk, beweging gaat hij uit, ipv aan.
Zelfs met de originele sketch van Arduino.
http://playground.arduino.cc/Code/PIRsense
Dan heb ik ook last een half brandende ledstrip.
Dus als ie uitschakeld, gaat hij niet helaaml uit.
dit gebeurd wel als ik de usb in mijn mega laat zitten.
Ik heb de ledstrip via een mosfet aangesloten, en die werk verder goed.
Dus eigenlijk hoef ik alleen maar 1 pin aan of uit teschakelen..
Dus HELLLLUPPP
Please..
Ik word er gek..
Zoiets simpels..

* The Parallax PIR Sensor is an easy to use digital infrared motion sensor module.
* (http://www.parallax.com/detail.asp?product_id=555-28027)
*
// * The sensor's output pin goes to HIGH if motion is present.
* However, even if motion is present it goes to LOW from time to time,
* which might give the impression no motion is present.
* This program deals with this issue by ignoring LOW-phases shorter than a given time,
* assuming continuous motion is present during these phases.
