It is a microcontroller for building digital devices that can sense and control both physically and digitally. "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 or a finger on a button - and turn it into an output - activating a motor, turning on an LED. 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, and the Arduino Software (IDE). We provide hands on training on Arduino uno by interfacing various kind of sensor which will collect real world data and we can further process that data according to our need. e.g Interfacing Led's with arduino,Switch interfacing,Burglar alarm,Automatic dark detector"
