Actually, 1.5mA is about the expected average LED current with that=20 combination (1K5 + 330nF). Try more like 2.2uF and 470 ohms for about 15mA average (resistor=20 dissipates less than 200mW) Or just replace the cap with a series diode and use 1K 1/2W for the resisto= r. --sp =20 --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
