Greetings all,
I am experiencing a challenging problem. Hope someone will be able to shed some light or give some tips / advice.
When writing / running / testing my sketch it runs 100% fine. As soon as I remove the USB Cable (PC <--> Arduino) the sketch no longer works. It will only continue with whatever is was last busy with.
This started to occur as soon as I added the PIR to my sketch. When my sketch was just the photocell and LED it ran fine (without the USB issue).
The closest similar description I have found to this was here: http://www.arduino.cc/en/Guide/Troubleshooting#toc5
- Arduino Uno
- Ubuntu 11.04
- Arduino IDE
- PhotoCell
- PIR
- LED's
- 12V PSU
Overview if the sketch:
If lightlevel is below threshold:
->Set LED to dim (analogWrite)
-->If PIR detects motion
--->Fade LED in and keep on for X cycles
Thanks in advance
