Cook up some ESP32 projects this weekend.

If you were on the fence about ESP32, these projects will get you started in no time ...

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 ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

If you’re working on an air quality monitoring project and space is at a premium, SparkFun’s latest Qwiic breakout board featuring Bosch Sensortec’s BMV080 sensor might be exactly what you need. This ...

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 ...

When comparing the Raspberry Pi and Arduino, it's no secret that the Pi is undoubtedly the more powerful board. It is, after all, a single-board computer (SBC) that can run a fully functional ...

Learning electronics? Then, chances are you already know what an Arduino is, or at the very least, you've heard of it. After all, it's among the most popular electronics platforms available in the ...

Thermal cameras can cost well into the five-figure range if you’re buying high-resolution models with good feature sets. New models can be so advanced that their export and use is heavily controlled ...
