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 ...

We made a skateboard wheel spin at 100,000 RPM, potentially setting a world record. The wheel was crafted on a lathe using aluminum and powered by our 60,000 PSI waterjet. #Skateboard #WorldRecord ...

Most modern vehicles come with two transmission speed sensors, which are responsible for monitoring the input and output shaft speeds of the transmission. These sensors send information to your car's ...

Speed variance—not just speed—drives crash risk. Higher average speeds raise deaths and big gaps trigger conflicts. Drive the lawful flow. “Slow equals safe” makes a great bumper sticker and a lousy ...

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.

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 ...
