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 ...

You would have probably read about the SONAR that’s used in ships. By taking the same concept into a small form factor we get a distance sensor. This sensor is available in multiple variants and I’ll ...

UV (ultraviolet) sensors of all sorts have been an interest of mine. They become interesting when you find the diversity of real-world practical applications. While searching for affordable UV light ...

The BME280 sensor was easier to set up, as it communicates over the I2C serial protocol. This means that we only needed to ...

Parking sensors have become a must-have these days given the crowded cities we live in, but instead of paying hundreds of dollars to get them installed in your car, why not build your own at home?

Discover Arduino Uno Q, a hybrid Linux plus microcontroller board with four Cortex A53 cores, so you get precise control and ...

The Arduino 101 equipped with Intel's Curie module integrates a 6-axis gyro/accelerometer and Bluetooth, which sets it apart from the rest of the Arduino line up. What the heck is an Arduino? Simply ...
