Arduino Nano Basics

Hello friends, I hope you are all very well. In today’s tutorial, I’m going to share basic details of Arduino NanoBoard. I have selected this topic because it is a more commonly used microcontroller board due to its flexibility, small size, and low cost. Furthermore, it is also the best microcontroller board for engineering students to design their final and semester projects. So let’s take a look at its basic features, properties and capabilities:

Arduino Nano Basics

• Arduino Nano is a microcontroller board designed and manufactured by the Arduino company.

• The microcontroller used in the Arduino Nano is Atmega328, which is also used in the Arduino UNO. The only difference is that Nano is in its SMD form whereas in UNO it is in DIP form.

• The operating voltage ranges from 5V to 12V.

Now let’s take a look at its basic features:

Arduino Nano Basic Features

• It has 22 I/O pins in total and 14 of these pins are digital while the remaining 8 pins are analog.

• It has 6 PWM pins between 14 digital pins.

• Analog Pins of Nano have 10 bit resolution and its value changes from 0 to 1024 and in terms of voltage it varies from 0V to 5V.

• It has a 16MHz crystal oscillator.

• In order to upload the code to it, we have to use a Mini USB Pin plugged into it.

• It supports different protocols for communication, which are:

1. serial protocol.

2. I2C protocol.

3. SPI protocol.

• Nano’s flash memory is 32kb and this is the memory where our loaded code is stored.

• Arduino Bootloader is pre-installed on this board and this bootloader occupies 2 kb of your flash memory.

• SRAM memory is 2kb.

• It has a 1kb EEPROM memory.

Now let’s take a look at its capabilities, so I’m going to take a look at some of its examples and applications.

Arduino Nano Applications

It is the most widely used microcontroller board and if I am not mistaken it has literally replaced the Arduino UNO due to its small size. In Embedded projects, size matters a lot, that’s why Nano is preferred over UNO. Now let’s take a look at some of its applications:

• embedded systems.

• Security systems.

• Automation systems.

• Medical instruments.

• robotics.

• Instrumentation.

• Virtual Reality Products.

The apps mentioned above are just the tip of the iceberg as we have a lot of them. I hope you enjoyed today’s tutorial, but if you have any questions or suggestions, please ask them in the comments and I’ll do my best to solve them all. You should also take a look at the Arduino Nano Pinout, if you’re thinking of using it in your project.
