INTRODUCTION Liquid crystal displays (LCD’s) are a commonly used to display data in devices such as calculators, microwave ovens, and many other electronic devices. In this tutorial, I will show you how to use a 16×2 LCD with an Arduino. 16×2 LCD is named so because; it has 16 Columns and 2 Rows. There are a lot of combinations …
This is a project to find Human speed. This system has a huge application in the field of sports. When we point the ultrasonic sensor straight towards the human and press the button, we will get the speed of that person. The speed is displayed on the LCD screen. We can use it to calculate …
This is a project used to count the number of people inside a room having a single door. It has so many applications in many places. For example, if there is a meeting arranged in a particular hall and food is providing after the session. The number of people inside the hall can be count …

by Shubham_ECE_UPES It is a type of sensor that will detect if the person has consumed alcohol and if he or she has then it will automatically stop the engine of the vehicle . It will prevent the accidents caused by drunk driving . Introduction We are in an era where accidents are too common …
Introduction We all have bought defective circuit components and suffered because of it. Here is simple and a handy tester which can test the components working condition. Components required NPN Transistors Battery (9V) Resistors (1KΩ) Capacitor (1μf) Switch LED (Green) Diode Circuit diagram Working Here two NPN transistors are used as switches. When the probes …
This project presents an Smart Room Temperature system capable to autonomously control the temperature level by exploiting data related to temperature in that specific area. The system is able to set the temperature level on the basis of required needs and allows one to remain in constant temperature. To this end, it makes use of …
Introduction During these hard times like the COVID 19, it would be suitable to use an automatic dispenser. This helps one to use hand sanitizer without any touch thus eliminating the passage of virus through non-living materials. The automatic dispenser senses the presence of hand using sensors and sent a signal to drop the sanitizer …

INTRODUCTION This DIY project is also famous with the name of Liter of Light. Liter of Light is the open-source design for a low-cost light tube that refracts solar light to provide daytime interior lighting for those houses which have thin roofs. Using Daylight is cheaper than using an indoor electric light during day time. …
INTRODUCTION:-This a very interesting project in which we are going to tell how can an arduino can check wheather a person is lieing or not.In this project we will connect our arduino nano digital pins with the leds(number of leds can be vary as per the requirement of the individual ) .We get our required …
IR Based Object Counter is an Infrared object counter build using Arduino. IR LED emits infrared light, means it emits light in the range of Infrared frequency. We cannot see Infrared light through our eyes, they are invisible to human eyes. The wavelength of Infrared (700nm – 1mm) is beyond the normal visible light. We …
INTRODUCTION A Geiger counter is an instrument used for detecting and measuring ionizing radiation. Also known as a Geiger–Muller counter (or Geiger–Müller counter), it is widely used in applications such as radiation dosimetry, radiological protection, experimental physics, and the nuclear industry. Today, we will make a mini Geiger counter using Geiger counter module, Arduuino and I2C 16*2 LCD Screen where we will …

An arithmetic expression that involves multiple operations such as addition, subtraction, multiplication, and division are not easy to solve as compared to operations involving two numbers. An operation on two numbers is easy but that in more numbers is difficult. So the rule used for doing these operations is BODMAS. BODMAS is an acronym and …
INTRODUCTION: In this blog we shall design a simple security system which can be used in Museums using Arduino UNO R3, Buzzer and few sensors. This type of Security system is used in Museums where an old or antique valuable thing is kept for display in glass box. Wondering How?? Let us begin with the …
INTRODUCTION Today, I am going to make an RF signal detector. So let come dive into the project. RF signal detector is used to detect the RF signals which are present within the range. Currently, mobile phones, walkie-talkies, radios uses RF signals for transmitting the data. Radio frequency is the oscillation rate of an …
