LPG Gas Leakage Detector Circuit using Arduino is important safety tool which can stop accidents, as this project uses Arduino to check LPG gas in air. Also, if gas level goes too high then buzzer make sound and LCD show warning, hence, through this circuit people know danger fast. Arduino Code: Code Explanation: Circuit Working: […]
Digital Thermometer Circuit using Arduino and IC LM35
This project builds a Digital Thermometer Circuit using Arduino and IC LM35, as first, the Arduino reads the voltage from the LM35 sensor, and then it converts this voltage into a temperature value. Moreover, people have used thermometers for a long time to measure temperature and then finally, the measured temperature appears on a small […]
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, also it have 7 LEDs inside and makes shapes for numbers and some letters. We can also connect it to Arduino and then it tells what number to show, as this article teaches how to connect 7-segment to Arduino UNO […]
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; also Arduino make PWM signal to control MOSFET gate. After that, MOSFET work like switch and control voltage to motor and changes speed. Arduino speed controller is simple and with low cost and it can […]
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 and it also switch between two states and each state have delay which we can change for different use. Arduino Code: […]
Battery Status Indicator Circuit using Flashing LED
Battery Status Indicator Circuit using Flashing LED is an easy to make project, as the circuit uses BC547 and BC557 transistor, some resistors, capacitors, one diode and one LED. LED show battery condition by blinking light and it work with 6 to 12V battery and it is easy way to know battery health and it […]
