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 ...

TDK Corporation has expanded Tronics’ high-performance MEMS inertial sensor portfolio with the launch of the AXO315®T1, a high-temperature digital accelerometer designed for energy sector drilling ...

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 ...

This video demonstrates how to set up a remote temperature monitoring system using an Arduino Uno R4 WiFi, an LM35 temperature sensor, and the MQTT protocol. The system captures ambient temperature ...
