Battery Voltage Drop Detection
I am powering a Basicstamp1 directly(no regulator) with a 9Volt alkaline battery and·same battery·is driving a H bridge to run a DC Latching Relay. When the battery voltage drops to about 6 volt I want Basicstamp not to drive H brige anymore. I tried to use a zenner diode to detect voltage drop but I havent been successful yet. One of the problems I have, I dont know what are the voltage limits for an Input Pin, I mean at what voltage it is 1 and 0. If zenner diode doesnt work is there anyother way to detect voltage drop.
Thanks

Keep checking the pin in software, as long as it is high, you have 6 volts or more. Low means under 6V.
