Ultrasonic sensor use high sound wave to find distance. It send sound and wait for echo to come back and then it measures time. With Arduino help we can make system to know how far object is. This project for Distance Measurement Circuit using Ultrasonic Sensor and Arduino shows basic of ultrasonic sensor, Arduino code […]

LPG Gas Leakage Detector Circuit using Arduino
LPG Gas Leakage Detector Circuit using Arduino is important safety tool which can stop accidents. This project uses Arduino to check LPG gas in air. If gas level goes too high then buzzer make sound and LCD show warning. Through this circuit people know danger fast. Code Programming and Explanation: Code Explanation: Circuit Working: Parts […]
Air Flow Detection Circuit
Air Flow Detection Circuit means basic electric circuit to check if air is moving or not. People use this in machines or home projects to watch air flow. In this project we make very simple circuit to see if air is moving. We used broken AC bulb and few cheap parts to feel air. This […]
Light Detector Circuit using Wheatstone Bridge
LDR change resistance when light fall on it. This is used in Light Detector Circuit using Wheatstone Bridge. One side of bridge has LDR and one fixed resistor in series. Other side has potentiometer and second fixed resistor in series. Voltage is given to two opposite corners of bridge. The output voltage taken from other […]
Simple Tilt Sensor Switch Circuit
Simple Tilt Sensor Switch Circuit control ON/OFF of LED or buzzer. Tilt sensor work like small seesaw switch. Inside a sensor there can be a small metal ball. When sensor stand straight the ball touch two points and then the current can pass. When sensor tilts the ball move away and the current stops. This […]
Simple Missing Pulse Detector Circuit
Simple Missing Pulse Detector Circuit is an electric circuit. It finds when pulse is missing in pulse signal. Most time it uses 555 timer IC and work like monostable multivibrator. When it gets trigger it gives one output pulse. If next pulse does not come in time then timer is in no reset. Output pulse […]
