Finally, eco-friendly music.

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 ...

Let’s face it: As we age, our vision and balance aren’t what they used to be. These changes to our senses can be minor annoyances but can also lead to injury, from stubbed toes to serious falls.

Shanling’s EC Zero T brings hybrid tube/solid-state sound to a portable CD player with R2R DAC, Bluetooth 5.3, and high-end headphone amp—CDs just got cool again. For those of us who refuse to let ...

This is a library for the Arduino IDE that helps interface with ST's VL53L4CD time-of-flight distance sensor. The library makes it simple to configure the sensor and read range data from it via I²C.

The discriminating space sensor is just one piece of the Defense Department's space-based missile-tracking architecture, which also features hypersonic and ballistic space sensor satellites, depicted ...

The Pixel 9 series has just been announced, and as you can see from the image below, the Pixel 9 Pro and 9 Pro XL still sport that small circle below the flash light. The temperature sensor is still ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...
