A small electronic horn is used to generate sound when the measured DC voltage differs from the reference voltage, which is determined by the linear wirewound potentiometer R7. Adjust R7 sound to null, then read the set braille point to get the measured voltage value . Use PNP silicon transistors such as BC177 or BC187.D5.
