This 555 Timer Astable Multivibrator Circuit is simple and easy; also astable means output never stays stable and output keeps switching high and low again and again. Moreover, the circuit creates square-wave pulses and drives LED blinking, tone generation, clock signals, and many hobby projects. Circuit Working: Parts List: Components Quantity Resistors 1k ohm, 100k […]
555 Timer Monostable Multivibrator Circuit
This article explain simple 555 Timer Monostable Multivibrator Circuit, as circuit create one single pulse when trigger comes; also time period depend on resistor and capacitor. Circuit is easy to build and can run from 5V to 12V power supply; moreover, many people use it for delay, timer, reset pulse and for buzzer control. Circuit […]
Rain Detector Circuit using Arduino
This project for Rain Detector Circuit using Arduino shows how to detect rain, here, rain sensor plate feels water drops. Then, the module gives analog and digital signals, and the Arduino reads these signals and finally, the LED glows when it starts raining. Therefore, this low-cost project is easy for beginners to build. Arduino Code: […]
Railway Track Accident Prevention Circuit using Arduino
Railway accidents happen because obstacles come on railway track, because many trains cannot stop fast; therefore, this project uses Arduino Uno, ultrasonic sensor, relay and motor or servo to give warning or stop mechanism. The system checks distance and if object comes close, relay activates and motor moves barrier or alarm system, also this helps […]
Arduino Based Pulse Monitoring Circuit
This project show how to make a simple Arduino Based Pulse Monitoring Circuit, as it uses Arduino Nano, pulse sensor, OLED display, buzzer, an LED; also the system reads heartbeat from finger sensor. Then Arduino calculate pulse per minute and OLED show result; after that LED and buzzer give alert when pulse go high or […]
IR Sensor Based Stick for Blind Circuit
This circuit turns a normal stick into a smart safety tool for blind users, as it helps blind person know if any object is near. Also, it uses an IR sensor, a transistor, a buzzer and a 5V regulator IC, here, the IR sensor detects objects that human eyes cannot see. Furthermore, this IR Sensor […]
