This sanitizer puts restriction for people to enter inside the door. #shops #atm #gates #letterbox

Diy - Relay Module
In this tutorial I am going to show you how to make a simple relay module that can be used in any project.

Covid Free Contactless Cordless Bell Using Arduino And Rf
This project is an attempt to make a simple touchless cordless bell, without spending a lot from your pocket.

Analog Speedometer Using Arduino And Ir Sensor
The project describes an analog speedometer where we have used IR Sensor to calculate speed.

Reed Switch
Just about everywhere you go, you'll find a Reed Switch nearby that’s quietly doing its job. Reed switches are so pervasive that you’re probably never more than a few feet away from one at any given time.

Simple 2fa Access System
We will build an access system that doesn't need any external devices( you can use an 13.56 Mhz RFID tag if you want), and that uses a private-public key system so password stealing is much harder, thus making your application more secure.

Build A Demo Matrix Keypad Lock With An Arduino
A demo project to read a 4x4 Keypad and drive a relay that controls a lock when the correct code is entered. It also has an OLED display to give the users prompt, a buzzer to provide audible feedback, and an override button to force the lock to open.

Covid-19 - Authorized Entry Using Face Mask Detection
The system is designed to detect unauthorized entry (face masks), that are essential to protect ourselves and to avoid spreading COVID-19.

Security System With Motion Detection
The system is designed to detect intrusion (unauthorized entry) into a building or other area.

Social Distance Thing
When social distancing was first introduced it was clear that not every person practised it properly or even at all. To help people visualize and become aware of the importance of social distancing we built the Social Distance Thing.

How To Build A Smart Door
A door, just smarter. Retrofit "smarts" into the traditional entrance and never leave your door unlocked again!

Door Alarm Using Arduino
Security is a major concern so we have designed a door alarm system to recognize the presence of anybody at the door.

Diy Webcam Spy-glasses
Looking for a project that uses your old, broken laptop? Make yourself a pair of DIY spy-glasses using the webcam! (You can also get a webcam online for $5). The project's quite east and a lot of fun!

Ardu Keyboard
Macro Keyboard based on ATmega328p

Surveillance And Reconnaissance Quadruped.
Quadruped means having four legs. So, I have designed and built a quarduped robot with four legs and a tail. It consists of 8 joints , 8 links and 1 main frame. A microcontroller and power source is fitted over it. It has proximity sensor for obstacle avoidance. A PIR sensor to sense human presence as a part of surveillance.

Iot - Touch Detection Using Touch Sensor & Led Bar
Build a simple touch detection system using a touch sensor and an LED bar for display.

Ac Voltmeter Using Arduino
We are going to create an AC Voltage Measuring Device using Arduino, which will estimate the voltage of Alternating Current.
