Arduino Projects by R

Hey everyone! Sorry I have not posted in a while. In this pandemic, all surfaces are prone to contamination. Scientists have discovered that UV-C can kill coronavirus, so today I will be presenting my Automatic UV disinfection robot which will be using UV-C rays to disinfect surfaces when humans are not around. UV-C rays are harmful to the human body so this robot has been programmed to stop moving and turn off the UV-C LED if human motion is detected.  Hardware components used in this project Arduino Uno USB Type A/ B cable Arduino Sensor Shield V5.0 IO expansion board L298N motor driver module Robot Chassis - 2WD beginner Gear Motor DC 5V (x2) Wheel (Robot car) Ultrasonic sensor module (HC-SR04) PIR motion sensor (HC-SR501) Micro servo motor SG-90 Ultrasonic sensor module mounting bracket Laser diode 5mm (UV-C is harmful to the human body so I've used a laser diode instead of the UV-C LED to demonstrate this robot) Rechargeable 18650 Li-ion 3.7V battery (x2) 18650 Li-ion 3.7V b...

Hey everyone! Today I will be explaining you about my new COVID-19 project. This project is about practicing social distancing more effectively with an automatic door control system, and will be helpful in public places such as Malls, supermarkets, railway station, ticket counters and other places where queueing is essential. The World Health Organisation, WHO, has advised people to practice social distancing (staying away from people for at least one metre) to prevent the spread of COVID-19 disease. In this project, the distance between the laser diodes are modelled as 1 m. Read on further to learn how I did this project.

Hey everyone! Today I am going to explain you about another interesting COVID-19 Arduino project. This is an automatic, effective and cheap method to limit the crowd in public places - such as shopping malls, supermarkets, offices, etc. - and public transport vehicles, such as buses and trains. The World Health Organization, WHO, has advised people to stay away from crowded places to protect themselves from the spread of Coronavirus disease. Even though people practice social distancing, it may not be effective when they are present in crowded places. I came up with this idea after I read the WHO guidelines about preventing the spread of COVID-19. Aim/ Objective This project is an automatic, cheap and effective way of limiting the crowd in public places and vehicles. Using a human to limit the number of people in a particular place would not be as effective as using an automatic system, due to lack of staff members in some areas. This prototype can be used in real-life situations by ...

Hey everyone! Today I will be explaining about my new project. I have made a touchless faucet with door control system. COVID-19 is a serious pandemic at this moment. The coronavirus is spreading quickly and easily between humans. There are ways to curb the spread of this virus and one way is to wash hands using soap for at least 20 seconds. Sometimes, if the person carelessly touches the faucet - which could be contaminated - after washing his/ her hands, he/she has a higher chance of contracting this coronavirus disease. If you go out, it is safe to wash your hands before entering your premises. You do not have to touch the door handle because the door lock system is automated. In my project, a person will only be granted access once he/ she washes his/ her hands. In this project, I have made a prototype to wash hands safely with automatic door control system. I have made an automatic faucet so that you do not have to touch the surface of the faucet. The prototype is cheap and easy ...

Hey Everyone! I hope that everyone's safe during this pandemic. Today I am going to explain you about the second version of my Buzz wire game. People who are bored of staying indoors can find this game pretty interesting and fun to play.  If you are a beginner, you can start off with my first version of this project :  51.
