Analogue Water Flow Sensor/Meter Circuit - Check Water Flow Rate. vol = (input * 5.0) / 1024.0; //formula using for perform action. The first digital multimeter was introduced in the late 1970s, and has proven much more accurate and reliable than the old needle-based analog meters. Without it, completing projects faces infinite difficulties. Using Ohm's Law (E=IR), we can determine how much voltage will drive this meter movement directly to full scale: E = I R E = (1 mA) (500 ) E = 0.5 volts If all we wanted was a meter that could measure 1/2 of a volt, the bare meter movement we have here would suffice. It can be used to measure battery voltage, sensor readings, etc. A voltage divider circuit is used to divide voltage into two parts. The microcontroller PIC 16F877A has 8 analog input channels for the in-built 10-bit ADC. So, the display will show in 1888.
