Anyone want to check speed of bike, car or any moving vehicle? So with Arduino and GPS module we can make small but cheap DIY speedometer, as this project for Arduino GPS Based Speedometer Circuit is easy and fun; also it shows real-time speed on LCD using GPS satellite data. This project requires only an […]

Arduino Based Motion Dog Barking Alarm Circuit
This Arduino Based Motion Dog Barking Alarm Circuit make dog sound when motion detects, it uses Arduino Nano, Pir sensor, Dog Sound Module, BC547 transistor, IC LM386 Amplifier Module and 8Ω Speaker. When Pir senses human or animal move, then Arduino play dog bark sound to scare intruder, also this is simple and low cost […]
Arduino Based Entry Exit Monitoring Circuit
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 […]
Arduino with Non Contact Liquid Sensor Circuit
An Arduino with a Non-Contact Liquid Sensor Circuit detects water or other liquids without touching them; therefore, it functions as a contactless sensor. Also, it works on capacitance change near container wall and sensor sense water inside plastic or glass without direct contact. Moreover, it is safe, easy and clean project one should give it […]
Arduino Piano Music Keyboard with Memory Circuit
This project is for Arduino Piano Music Keyboard with Memory Circuit and its main parts are Arduino Uno, push buttons, buzzer, LCD and resistors. When button is press then buzzer make piano sound, LCD show note name on screen and then we can record notes and play again later. Furthermore, it is small and fun […]
