Acceptable Voltage Indicator |
I have used this circuit many times in custom test fixtures where a simple go-no go
indication was needed. This hobby circuit can also be used to adjust a
particular voltage be within specific high or low limits. The three LEDs will
indicate if the voltage is high, low or OK. When connected to other
converters, such as a frequency to voltage converter, a current to voltage converter
or a power to voltage meter, it could provide a quick indication of a proper level. |
