Sensors And Actuators
Let us discuss about sensors and actuators :
Sensors
The term ‘sensor’ is self-explanatory and indicates a device that can sense any physical quantity and convert it to a form that can be measured like a signal. Sensors can be categorized into different forms depending on the type of quantity they measure. For example, the temperature sensor is a device that measures temperature.
The most common example of a sensor is an analog sensor that can be used for measuring a continuous range of values generally from 0-5V. Another type of sensor are digital sensors that sense inputs and then generate an output in digital bits. Certain libraries have been designed to read this digital sequence generated by the sensor for measuring purposes.
This line of code is used for reading the value.
sensorValue = sensor.read();
Actuators
Contrary to sensors, actuators are used to change a physical state based on something they sense. Actuators perform the task of using the signal to actuate something like causing mechanical movement when an input is sensed or turning a light bulb on when voltage is received.
Let us see how digitalWrite() and analogWrite().
digitalWrite(LED, HIGH); //turn on an LED
digitalWrite(LED, LOW); //turn off an LED
analogWrite(motor, 255); //set a motor to receive 255 bits
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.
