- 24 Best Arduino Nano Projects that you must try 2022
Introduction to Arduino Nano v3
The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.0).
It offers similar connectivity and specs to the Arduino Uno Rev3 and lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one.
Based on the ATmega328P the Arduino Nano is good for beginners to start on the Arduino! To know more about the ATmega328P, you can check out our other blog here!

Seeeduino Nano – Alternative to the Arduino Nano
Feel that the Arduino Nano is too expensive and looking for an alternative? No worries, as Seeed got the solution for you with our Seeeduino Nano:
The Seeeduino Nano is a compact board that is fully compatible with the Arduino Nano on pinout on sizes.
The first you will realise about the Seeduino Nano is the price of it. It only costs $6.90 which is 6 times cheaper than the Arduino Nano! Afraid that the specs will be compromised due to the low cost? No! Not only does the Seeduino Nano offer the same features and high-quality experience as the Arduino Nano, but we have also made some improvements on it which are:
- Mini – USB to Type -C which is symmetrical and reversible
- Addition of 1 Grove Connector where with the help of our Grove system, you can easily plug and play with hundreds of sensors and actuators.
Here is a table comparing both of them!
| Model | Processor | Input Voltage | IO Voltage | Analog in/out | Digital IO / PWM | USB | Grove Connector | Price |
| Seeeduino Nano | ATmega328P | 5V / 7-12V | 5V | 8/0 | 14/6 | TYpe C | 1 x I2C | $6.90 |
| Arduino Nano | ATmega328P | 5V / 7-12V | 5V | 8/0 | 14/6 | Mini – USB | – | $45.90 |
Without further ado, let us jump right into the 24 Best Arduino Projects that you must try in 2022!
