Using these devices I have built a base station for wireless sensor nodes (with RFM12B). It works well for approximately 6h. After that the code seems to freeze and the LED next to pin 10 blinks rapidly. Reset does not help. When I remove the power source and reattach it, everything starts to work again. My code can be seen here: http://pastebin.com/ytdVHqtu
LED labels on my ethernet shield are fuzzy. Can anyone tell me what indicator LED is next to pin 10? Rightmost on this image: http://www.sainsmart.com/zen/albums/SKU/20/20-011/20-011-C83/20-011-C83/06.JPG
Ideas why the code freezes are also very welcome :)
If anyone suggests some good site where schematic can be drawn online then I can create that scetch as well...
