Flash Bee is an easy-to-make DIY handheld lightning detector based on an ESP32-C3 board, a round display, and AMS AS3935 ...

The best smart thermostats we've tested can control your home's heating and cooling with your phone or voice—and might help you save on energy costs. I’ve been working with computers for ages, ...

In this video I'll be showing you how you can control the contrast and the back light brightness of a 1602 LCD display with just the Arduino. The contrast is typically adjusted with a variable ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Whenever the temperature climbs, we all see social media posts of car dashboards offering blisteringly hot temperature claims, but how accurate are they? As the big question is, really, where is the ...

Over the past decades, physicists and quantum engineers introduced a wide range of systems that perform desired functions leveraging quantum mechanical effects. These include so-called quantum sensors ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

One of the joys of writing up the entries for the 2025 Component Abuse Challenge has come in finding all the different alternative uses for the humble transistor. This building block of all modern ...

AM232X is a sensor similar to the DHT12 with an I2C interface. Although in theory this could enable multiple sensors on one bus the AM232X has a fixed address 0x5C so one need to implement a ...

Abstract: This article proposes a temperature-humidity assembled sensor based on AlScN surface acoustic wave (SAW) technology for simultaneous monitoring of temperature and humidity. The assembled ...
