Blinking an LED with Delay – Arduino Basics

Last Updated on May 14, 2026 by Swagatam 4 Comments

arduino sketch

Here I have explained the bare minimum code for compiling an Arduino and also the method of blinking an LED using an Arduino board. Learning the Bare Basics Here we discus and try to understand the fundamental minimum code that one would need to compile an “Arduino Sketch” which consists the setup()method and the loop()method. […]

Converting Analogue to Digital (Analogue Read Serial) – Arduino Basics

Last Updated on May 14, 2026 by Swagatam 3 Comments

In this Arduino basics I have explained the code implementation procedure wherein an external analogue signal is fed to the Arduino analogue input and translated or converted into a correspondingly proportionate digital readout. Here we employ a variable resistance in the form of a pot as the analogue signal source. Analog Read Serial In this […]

How to Make LED Air Pollution Meter Circuit with Arduino

Last Updated on May 14, 2026 by Swagatam 3 Comments

In this project I will show how to construct an air pollution meter using MQ-135 sensor and arduino. The pollution level in the air is indicated by series of 12 LED. If higher the number of LEDs glows, the higher the pollution content in the air and vice versa.   Overview This project can prove […]
