# What is the sampling rate of an Arduino Uno?

## What is the sampling rate of an Arduino Uno?

Arduino itself provides a convenient way to read analog input using analogRead() function. Without going into much details, the analogRead() function takes 100 miliseconds leading to a theoretical sampling rate of 9600 Hz (9600 samples each second).

## What is the maximum conversation speed of Arduino Uno ADC?

On ATmega based boards (UNO, Nano, Mini, Mega), it takes about 100 microseconds (0.0001 s) to read an analog input, so the maximum reading rate is about 10,000 times a second. **The default analogRead() resolution for these boards is 10 bits, for compatibility.

## What is the conversion speed of Arduino Uno ADC?

For a 16 MHz Arduino the ADC clock is set to 16 MHz/128 = 125 KHz. Each conversion in AVR takes 13 ADC clocks so 125 KHz /13 = 9615 Hz. That is the maximum possible sampling rate, but the actual sampling rate in your application depends on the interval between successive conversions calls.

## How does the sampling rate work on an Arduino Uno?

For a 16 MHz Arduino the ADC clock is set to 16 MHz/128 = 125 KHz. Each conversion in AVR takes 13 ADC clocks so 125 KHz /13 = 9615 Hz. That is the maximum possible sampling rate, but the actual sampling rate in your application depends on the interval between successive conversions calls.

## What are the specifications of the Arduino Uno R3?

The Arduino Uno R3 board includes the following specifications. It is an ATmega328P based Microcontroller. The Operating Voltage of the Arduino is 5V. The recommended input voltage ranges from 7V to 12V. The i/p voltage (limit) is 6V to 20V. Digital input and output pins-14. Digital input & output pins (PWM)-6.

## What kind of communication protocols does the Arduino Uno use?

The communication protocols of an Arduino Uno include SPI, I2C, and UART serial communication. An Arduino Uno uses the two functions like the transmitter digital pin1 and the receiver digital pin0. These pins are mainly used in UART TTL serial communication.

## Is there a maximum reading rate for Arduino?

on 6 Mar 2017. Although the maximum reading rate for the analog pin is 10 kHz, this speed cannot be guaranteed with serial communication via Arduino and MATLAB. In other words, there is overhead involved by calling the “readVoltage” function in MATLAB, collecting the signal value from the Arduino pin, and sending it back to MATLAB.
