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
