The two resistor voltage divider is one of the most basic and common circuits in electronics. It is often the first circuit a beginner learns. A voltage divider turns a large voltage into a smaller one. How it works is, the ratio of the resistors (R1 and R2) divides the input voltage down to a lower output voltage. The output voltage is a fraction of the input voltage, and that fraction is R2 divided by the sum of R1 + R2. The formula is VOUT = VIN * (R2 / (R1 + R2)) . The voltage divider calculator assumes
Voltage dividers are commonly used for scaling down the voltage input to an ADC channel. For instance, if you want to read the voltage of a 12 volt power source but your ADC has a maximum input level of 5 volts, the voltage divider will scale the voltage down to a safe level.
Many sensors are resistive and it's not possible for an ADC to get a proper reading from them. By adding a resistor to the resistive sensor, you create a voltage divider. Once the output of the voltage divider is known, you can calculate the resistance of the sensor.
