The hardware setup shown below includes the Arduino Uno R4, a DHT11 sensor, and the built-in Wi-Fi for email alerts. The DHT11 is connected with VCC to 5V, GND to ground, and the data pin to Digital ...

A maker shared an electronics project on Digikey that explains an automatic system for recognizing and organizing resistors using an Arduino Uno Q. Zach Hipps did the work and looked for methods to ...

The source code is coming soon.

The QR code is so small, in fact, that it can "only be recognised with an electron microscope". As a result, the research ...

The land is a mix of fields, houses here and there, what appears to be farmland, and a mix of signage for incoming developments.

The best father-son hobbies aren't about killing time - they're about building something together that teaches your kid how ...

Tools such as Cursor can go a long way toward simplifying code setup. There's still a lot of work to refine the results. Conceiving an app's goals and how to get there is the hidden gotcha of AI ...

Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, and turning off when the sensor is released. The testing of the keys ...

SINGAPORE – An app is being developed to help Singaporeans detect fraudulent QR codes that lead them to harmful sites when they are trying to access government services instead. Currently available ...

Bruce Kingsley used an Arduino project board to add sound, motion, and programmed lighting effects to this HO scale house. You can read his story and other Arduino ...

This is a DIY Arduino-based overcurrent relay project that emulates Inverse Definite Minimum Time (IDMT) protection using an Arduino Nano and ACS712 current sensor. Instead of traditional ...

Air pollution is a critical concern in modern living environments, particularly in enclosed spaces such as homes, offices, factories, and laboratories, where prolonged exposure to harmful gases ...
