How to Make an Arduino Ohm Meter - Circuit Basics
Voltage divider is a resistive circuit and is shown in figure. In this resistive network we have two resistors. As shown in figure, R1 and R2 which are of 10k and 100k ohm. The midpoint of branch is taken to measurement as a anolog input to the Arduino. The voltage drop across R2 is called Vout , that’s the divided voltage of our circuit
Measuring voltage on an Arduino - KRAKKUSCOM
For example, an ADXL345 accelerometer allows for a maximum input voltage of 3. 3V, so if you try to interface it with an Arduino (assume operating at 5V), something will need to be done to step down that 5V signal to 3. 3V. Voltage divider!
Arduino Playground - Waterlevel
The ADC measures all the voltages associated with supervision and protection; battery voltage, boosted voltage, charging sense voltage and output voltage are conditioned through voltage divider network for feeding the ADC range, which is 0-1. 1 volts here. I have used the INTERNAL REFERENCE of Arduino which creates an reference voltage of 1. 1 volts.
Measuring DC Voltage with Arduino and Node-RED - PDAControl
Stack Exchange Network. Stack Exchange network consists of 175 QA communities including Stack Overflow, High voltage measurement with an Arduino. I though about using a voltage divider with the lower resistor having a bypass Zener to protect from over voltage, but that would require very large resistances (8~10 GOhms, and I'm mounting
EVAL-ADE9000-Shield Evaluation Board - Analog Devices
Software Voltmeter Circuit Diagram. The circuit uses a voltage divider on each channel to increase the readable range of the Arduino analog inputs from 5V to about 50V. For an explanation on how Arduino measures voltage, read the article on measuring DC voltage using Arduino.

2/11/2017Many will say to measure DC voltage in Arduino easily, but in this case I bring a relatively safe method for our circuits and maybe precise, you can see it working in this Dashboard in Emoncms

LOW COST PRECISION MEASUREMENT SHIELD FOR ARDUINO
Remember that when you measure a voltage (Vi) into an Arduino ADC, you'll get a number. Rewire as shown, the 10K resistor is still connected to the higher voltage, and the thermistor to ground. This sketch takes those two improvements and integrates them into …
