any pointers on pulse driving LEDs ? Assuming a standard 10mA 5mm LED, what sort of repetition frequency and max current would be suitable for a led that has a duty cycle of 8%, ( illuminated for about 0.07 seconds each second ) are there any manufacturers guidelines about this? -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
