> how I could possibly make this work? Hi Dan, is the IR modulated ? What you'd ideally aim for is to make the ambient light level the same whether indoors or outdoors. Or at least minimise to the max ambient light outside so the IR can stand out. Do you have a specific light filter ? -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
