Power the inverter from 10V. Tjaart: If I correctly understand what you're describing, that method works even WITHOUT the inverter... A 2.5-volt drop across the LED is enough to light it, so you can just put the bicolor LED between the PIC and the voltage divider. -Andy === Andrew Warren - fastfwd@ix.netcom.com === Fast Forward Engineering - Vista, California === === Custodian of the PICLIST Fund -- For more info, see: === http://www.geocities.com/SiliconValley/2499/fund.html
