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. We use 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, IC 7809 and […]
Solar Tracking Circuit using Arduino
Today solar power is very important because world need clean and green energy. Solar tracking help make solar panels work better. It move solar panel with sun all day so panel get more sunlight and gives more power. Solar Tracking Circuit using Arduino is smart, DIY and fun project. Arduino is open-source board which is […]
DIY Temperature-Controlled Fan Circuit with Arduino
Modern devices and homes need good temperature control. It help gadgets live long and make place comfortable. One example is fan with temperature control. Fan change speed by room temperature. This keep temperature okay, save power and with less noise. IC LM35 sensor is used for check the temperature. When it is too hot 5V […]
Arduino Based Air Quality Monitoring Circuit
Arduino Based Air Quality Monitoring Circuit check bad stuff in air like CO2, VOCs and PM. It uses Arduino microcontroller and many sensors to check air quality. Arduino read sensor data and then send to computer or cloud or show on small screen (LCD). People like this design because it is cheap, easy and useful […]
