Circuit Basics
Consider this basic LED circuit
Consider the circuit shown above, the LED is connected to pins on the Arduino using some resistors to limit the amount of current flowing through the LED. The reference level is set using the ground pin.
During the high or the ‘ON’ state, the circuit connections will be complete, and current will flow through the circuit components as programmed in the microcontroller. In this state, the LED will glow. When the circuit is turned ‘OFF’, the pins are set to low and the LED becomes dim due to no current flow.
Getting Started With Arduino
Arduino is an important device used in electronics engineering for creating mini-projects or for integrating large projects. Arduino itself consists of various components that can be programmed according to the project requirements using some assembly languages like C/C++.
Arduino is the first choice of many professionals due to the ease with which it can be programmed and how it allows interactive features for user experience. Arduino is programmed to include both hardware and software components which account for its use in different fields like designing, sensing, and testing.
Since Arduino is an open-source platform, it is used globally by users all across the globe. Let us study what is an Arduino, what functionalities it has and how can we use it in daily life.
