Hello World for Sensors With Arduino
You have obviously heard of the Arduino boards and how they have revolutionized hobby electronics.Here is a little primer to get you started. you have heard a lot about 'Internet of Things' and probably bought yourself an arduino kit along with a few more sensors but you can't figure out how exactly use them! If that sounds like you,then you are at the right place. Here's what you will need: An Arduino uno(Obviously!) Jumper wires(Make it yourself!) Breadboard(Optional,but helpful) Arduino IDE There are undoubtedly a lot of sensors available and covering all of them wont't be feasible and that's why I'll cover the most frequently used sensors.so let's get started! Ultrasonic Distance Sensor You would have probably read about the SONAR that's used in ships.By taking the same concept into a small form factor we get a distance sensor.This sensor is available in multiple variants and I'll be using the 'HC-SRO4' variant.
