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 […]
Digital Thermometer Circuit using Arduino and IC LM35
This project make digital thermometer using IC LM35 sensor and Arduino. Arduino reads voltage from LM35 and changes it to temperature number. People use thermometer for long time to check temperature. Temperature show on small LCD screen for easy see. With Arduino we can build thermometer that show real-time temperature on screen. It can be […]
Interfacing a 7-Segment Display Circuit with Arduino UNO
Interfacing a 7-Segment Display Circuit with Arduino UNO is small electric part which shows numbers. It have 7 LEDs inside and makes shapes for numbers and some letters. We can connect it to Arduino and then it tells what number to show. This article teaches how to connect 7-segment to Arduino UNO and show numbers. […]
DC Motor Speed Controller Circuit using Arduino
This project for DC Motor Speed Controller Circuit shows how to control DC motor speed using Arduino, MOSFET and potentiometer. Arduino make PWM signal to control MOSFET gate. MOSFET work like switch and control voltage to motor and changes speed. Arduino speed controller is simple and with low cost. It can control motor, light and […]
Arduino 2-Step Programmable Timer Circuit with Independent Output Delay Adjustment
This project for Arduino 2-Step Programmable Timer Circuit with Independent Output Delay Adjustment uses Arduino microcontroller to make simple timer. Not like normal timer with two outputs as this one uses only one output. It switch between two states. And each state have delay which we can change for different use. Circuit Working: Parts List: […]
