This project demonstrates how to build a simple yet effective Smart Blind Stick using an Arduino and an ultrasonic sensor. The system provides buzzer and LED alerts that vary their rate based on the ...

Another simple circuits for PWM programming of standard regulator chips, this time Vout is programmable down to zero volts.

Integrating a shunt resistor and Hall-based current sensor into a single device helps simplify EV architectures and enhances ...

🛠️🌍 Wi-Fi controlled four-wheeled scout vehicle using dual Arduino Uno R4 boards, ultrasonic sensor, turret rotation, and LCD display for real-time obstacle detection.

The circuit makes it possible to obtain a high signal-to-noise ratio by effectively transferring signal charges accumulated in the photodiode to a small capacitance. We fabricated and tested a CMOS ...

This DIY seismograph project uses a sensitive vibration sensor to monitor tremors, including those too subtle for humans to feel. Want to detect earthquakes and other seismic events—from natural ...

A simple transistor circuit offers an effective solution to this problem. The I 2 C bus is highly vulnerable due to its design — both SCL and SDA “float” at high potential and are pulled low by the ...
