However, the Arduino only supports reading from 0v to 5v maximum. I'm trying to read voltage using Arduino, here's the code: float r1 = 99700; float r2 = 10004; float adc, voltage; unsigned long analog; void setup () { Serial.begin (9600); analogReference (EXTERNAL); pinMode (A0, INPUT); } void loop () { for (int i = 0; i < 64; ++i) { analog += analogRead (A0); delay (1); } analog = analog / 64; adc = Reads the analog value which is converted from the voltage from the specified analog pin. Arduino boards contain a multichannel, 10-bit analog to digital converter. This means that it will map input voltages between 0 and the operating voltage (5V or 3.3V) into integer values between 0 and 1023. 2018-08-29 You are reading a voltage (analogRead(lightPin)). You can convert your ADC reading to a voltage by this process: percent = (adcNumber / MaxADC) voltage = percent * MaxVoltage So for you.
Division Factor is voltage divider ratio = Vin/Vout. Figure 1: Voltage Divider Circuit. Arduino can measure voltage with reference to ground only. Components Used for DC Voltage Measurement. 9K, 1K Resistors; Arduino Uno; Connecting Wires Luckily, nearly all microcontrollers have a device built into them that allows us to convert these voltages into values that we can use in a program to make a decision. Here are some topics and concepts you may want to know before reading this tutorial: Voltage, Current, Resistance; Binary; Analog vs Digital; Arduino analogRead() Voltage Dividers The ZMPT101B is a voltage transformer used to measure AC voltage.
from the temperature sensor int reading = analogRead(sensorPin); // converting that reading to voltage, for 3.3v arduino use 3.3 float voltage
The default reference voltage is 5 V (for 5 V Arduino boards) or 3.3 V (for 3.3 V Arduino boards). 2011-01-11 · Therefore at certain resistance values, analogRead() will return certain numerical values. So, if we created a circuit with (for example) five buttons that allowed various voltages to be read by an analog pin, each voltage read would cause analogRead() to return a particular value.
The ZMPT101B is a voltage transformer used to measure AC voltage. You can measure AC voltages up to 250 volts by using this module. The output of this sensor is analog. if you change input voltage, the output voltage will change as well.

By multiplying sensorValue by (5.0/1023.0), it scales down the range from 0-1023 (which is the range that analogRead () returns) to the range 0-5 which is the actual range of the voltage.
