#530: Arduino UNO R3


The Arduino Uno R3 is the entry point for anyone interested in robotics and microcontroller programming. 

It is designed to be easy to add and remove components without soldering. It is essentially a small computer that can be programmed.

Can be powered by battery, from a wall-plug or directly from a USB-cable from your computer.

The Arduino makes electronics easy and instead of having to worry about resistors, capacitors and inductors, you can simply focus on purchasing modules that will accomplish what you need for your project.

This is the open-source (and much cheaper) version of the Official Arduino Uno R3. 

All the information you need to get started with Aruinos can be found at 


The Arduino has taken South Africa by revolution all the way from Johannesburg to Durban to Port Elizabeth to Cape Town! Yet ironically enough, the Arduino is often used in rural settings far away from the cities, running on only on a solar panel and batteries.
