Arduino Uno Development Board

Original and the best Uno board

The Arduino UNO is a development board which features the ATmega328P microcontroller (MCU). It is a perfect introduction to electronics and coding. The UNO also demonstrates the basics on sensors and actuators. The UNO is the ideal, entry-level board for those who are new to developing on the Arduino platform. It’s a popular board as it is really robust when it comes to tinkering. For those more experienced, it’s still the perfect board for rapid prototyping. 

The board contains everything it needs to support the ATmega328P MCU. Just connect it to PC via USB cable or connect it to an AC-to-DC battery. The Arduino Software (IDE) is there to help but the UNO is a sturdy board. You can tinker to your heart’s content without having to worry too much about breaking it. And, if something does go wrong, you can always replace the chip. 
There is also a community surrounding Arduino which is there with lots of support. So, if you’re ever stuck, just reach out for help. There is also tonnes of resource to help inspire you with your next project. https://www.arduino.cc/
