In this article we are going to see how to build a home security system circuit using arduino which might save your home from intruders one day. Housebreaking happens every few seconds in the world. By the time you read this sentence, crooks already broke into someone’s house. A golden rule: Prevention is better than […]
Newly Updated Circuit Projects:
Make this 7 Segment Digital Clock with Beep Alert Circuit
In this post I will show how to construct a digital clock using 7 segment LED display with Arduino controlled design. How the Circuits Works The proposed 7 segment clock circuit is inexpensive and even beginner in Arduino can accomplish it with ease. This clock consists of four 7 segment displays, two for hours and […]
How to Make LED Air Pollution Meter Circuit with Arduino
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 […]
GSM Fire SMS Alert Project
In this article I will show how to construct a GSM fire alert circuit system using Arduino and DHT11 sensor, which will alert the user via text message (SMS), regarding a fire hazard within the premise where it is installed. Using DHT11 Sensor We are using DHT11 sensor for sensing unusual temperature rise around the […]
Password Security Lock Circuit Using 4×4 Keypad and Arduino
In this post I will show how to construct a password security lock circuit, which can be accessed by a 6-digit password. To be more precise it is alpha numeric password. Hardware for this Project We are going to utilize 4×4 keypad, which consists of 0 to 9 decimal values, two special character ‘#’ and […]
How to Make a Simple Math Calculator using Arduino
In this post, I will show how to construct a calculator using Arduino, which can perform far complex arithmetical calculation than an ordinary calculator. Program: //——————-Program Developed by R.Girish—————// #include<math.h> float a = 500; float b = 105.33; float add; float sub; float divide; float mul; void setup() { Serial.begin(9600); Serial.println(“Simple Arduino Calculator:”); Serial.println(“n”); Serial.print(“a […]
