I have a bs2 stamp and want to control a relay. I want the stamp to monitor a voltage and when the voltage gets to 12.5 volts turn off a relay. Any ideas where to find some information on this project?
In terms of turning a relay on and off, look at Nuts and Volts Column #6 (look here).
In terms of monitoring a voltage, you can use the RCTIME statement to measure a slowly changing voltage. EmeSystems has information on this (here). Look under the RCTIME statement and measuring battery voltage.
Both the Nuts and Volts Columns and the EmeSystems website have lots of useful information on using Stamps. Browse through them.
