In Arduino programming, comparison or relational operators are used to compare values and make decisions based on the results of these comparisons. These operators help you create conditional statements that control the flow of your program. Checkout this article to learn more: playwithcircuit.com/using-comparison-or-relational-operat...
In our daily life, we come across various devices that has LCDs to display data such as calculators, microwave ovens, and many other electronic devices. These LCDs can be used to display data from the Arduino or any sensor connected to it. For example, you can create a temperature sensor system which displays the temperature data on your Arduino. Therefore, LCD is very useful output device for your Arduino. In this tutorial, we will learn about how to interface a 16×2 LCD with an Arduino UNO and how to display custom characters on the LCD.
An infrared (IR) sensor module is an electronic device that detects and measures infrared radiation in its surrounding environment. It can be easily interfaced with the Arduino. In this tutorial, you will learn about the Infrared proximity sensor module, how it works and how to interface it with Arduino.
