The circuit, is a
comparator, can measure with step of 1Volt, the voltage of battery of car. The clue of
voltage become after comparison of voltage of battery, that is applied in the inverting
inputs of amplifiers, with voltages of reference that are produced by a Zener D1, the
value of which is such so that it present good thermic stability. With the RV1, we
regulate the gradation of voltage that we want. The optical clue become from four Led. |
