We show how to make Simple Alcohol Detector Circuit using IC LM393 This circuit uses LEDs, resistors, capacitor, MQ-3 sensor and LM393 IC. Alcohol detector find alcohol gas in air and give warning through light or sound. Today in this article we will talk about MQ-3 sensor. MQ-3 is common sensor for alcohol which is […]
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 […]
