Precise voltage measurement with an Arduino microcontroller

The Arduino board contains a 6 channel, 10-bit analog to digital converter. This means that it will map input voltages between 0 and 5 volts into integer values between 0 and 1023. This yields a resolution between readings of: 5 volts / 1024 units or, . 0049 volts (4. 9 mV) per unit.

Tutorial 20: Arduino Analog Input Output - Programming

The pins on the Arduino can be configured as either inputs or outputs. This document explains the functioning of the pins in those modes. While the title of this document refers to digital pins, it is important to note that vast majority of Arduino (Atmega) analog pins, may be configured, and used, in exactly the same manner as digital pins.

Lab 2: Digital Input and Output with an Arduino – ITP

We will also learn about multimeters which are used to measure voltage, resistance and current the three components of Ohms Law, a fundamental concept of basic electronics. Finally we will also learn how to use the Arduino IDE built-in plotter. To follow along, download the Analog Input Worksheet and print it (link above) Hardware:

Tutorial 09: Reading Analog Pins and Converting the Input

A typical circuit to connect a variable resistor to an Arduino analog input . As you can see, in some way, the circuit is very similar to the one used when connecting a digital input to Arduino. It also uses a 10K ohm load resistor to prevent a short circuit in case the photocell internal resistance decreases down …

Physical Computing - Scratch for Arduino - Arduino Project Hub

The Arduino Pro Mini is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, an on-board resonator, a reset button, and holes for mounting pin headers.

Analog Inputs - Microcontroller Programming

ANALOG INPUTS (ANALOG TO DIGITAL CONVERTER) Different AVRs have a different number of analog Inputs the ATmega8 and the ATmega168/328 has 6 different device pins but only 1 ADC (Analog to Digital Converter) converter. The 6 input pins are connected to a multiplexer which basically allows a single input to be connected to the ADC in

Arduino analog measurements :: Electronic Measurements

Arduino analog inputs can be used to measure DC voltage between 0 and 5V (on 5V Arduinos such as the Arduino Uno when using the standard 5V analog reference voltage). The range over which the Arduino can measure voltage can be increased by using two resistors to create a voltage divider.
