This Arduino Entry Exit Monitoring Circuit counts people while entering and leaving place, it uses Arduino UNO R4 WiFi board. Two IR sensors detect people and two servo motors control entry and exit gates and then sends crowd count to Arduino IoT Cloud. Hence, this help us know how many people are inside anytime. Arduino […]

Water Quality Test Circuit using Arduino and Turbidity Sensor
Water may look clean, but it can contain hidden dirt that we cannot see; also tiny particles such as dust, clay, and silt make the water cloudy and we call this cloudiness turbidity. More turbidity means more dirt and bad water and less turbidity means clean and safe water; therefore, this project uses Arduino and […]
Simple Micro SD Card Data Logging Circuit with Arduino UNO
Accurate data logging is very important in electronics and data work. This project for Simple Micro SD Card Data Logging Circuit with Arduino UNO show how to use micro SD card, IC 7809 and LM35 sensor to make simple data logger. Also, it saves temperature data to SD card and later we can check data […]
Building a Smart Pet Feeder Circuit using Arduino
Feeding pets can be easy and on time using automatic system. This project for Building a Smart Pet Feeder Circuit using Arduino and other parts like IC 7809, SG90 servo motor and HC-SR04 sensor to make simple pet feeder. Feeder work with distance sensor to give food so pet can eat on time without people […]
Human Presence and Motion Sensor Circuit using Arduino
This project uses electronic and integrated technology for energy saving, smart places and safety system. Main idea is to sense human presence and movement and for that we used mix of sensors and microcontroller to do this work. In this tutorial for Human Presence and Motion Sensor Circuit using Arduino we have used STHS34PF80 sensor, […]
