Arduino

Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing.

With the Arduino you can create EVERYTHING ... Just EVERYTHING. Knowing the principles of microcontroller programming and the principle of the board, you can create computer systems with any logic. Electronics programming is difficult process, but there is a place where you can learn this.

Useful origin for stading Arduino is a site of Arduino.

And the YouTube channel " Programming Electronics Academy" is a very useful origin to learn the world of any electrical boards and electrical circuts.
