This makes the Arduino send SMS, even though it doesn't use any GSM modules at all. Here, to send SMS alerts, I am using the Circuit ... flame sensor or smoke sensors detects fire and smoke. At the ...

You should also consider the sensitivity of the movement sensor: the part of the alarm that detects whether your bike is being meddled with or not. Although you may not know how sensitive it is ...

An Arduino project implementing a security alarm system featuring PIN code access via a 4x4 keypad, status updates on a 16x2 LCD, motion detection using an HC-SR04 ultrasonic sensor ... to include a ...

Abstract: Mass production of widely used semiconductor digital integrated circuits (ICs) has lowered unit costs to the level of ordinary daily consumables of a few dollars. It is therefore reasonable ...

At the core of the system, a sensor chip comprising 32 macro-pixels based on an array of single-photon avalanche diodes featuring an optical fill factor of 70% was fabricated in a 0.18-μm CMOS. The ...

In this session, you'll assemble a multiple electronic circuits around an Arduino microcontroller including lights and sensors. You'll learn how to tell such a microcontroller what you want it to do!

Elektor’s May/June 2025 edition features innovative test and measurement projects, including a crystal tester, a milliohmmeter adapter, the PbMonitor battery monitor, and more. Enjoy the magazine!

This is a project to explore a method to measure very small magnetic fields, which was invented in 1937 by Friedrich Förster, known under the names Förster-probe or Fluxgate sensor. I describe a DIY ...

The 555 timer is a versatile integrated circuit (IC) that can control timing in electronic circuits. It's one of the most widely used ICs due to its reliability and flexibility.

The device uses an ultrasonic sensor to detect nearby obstacles and provides real-time audio feedback, helping users navigate their environment more safely and independently.
