New technology enables light to be stored, delayed, and controlled within a single photonic chip, with potential applications ...

Cook up some ESP32 projects this weekend.

Using the new Vera C. Rubin Observatory, astronomers are beginning the largest and deepest survey of the sky. What will they ...

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

A Raspberry Pi, an Adafruit 7-segment display, a 3D printed case, some vibe coding—and we've got a forever-clock that never ...

MIT engineers have found a way to give chip-based lidar a wider, clearer view without relying on moving parts. Their design uses differently shaped antennas that can sit close together without ...

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 ...

We may receive a commission on purchases made from links. Since it would be challenging to find all the different types of sensors in one place, we decided to put together a list of some of the best ...

Today’s best robotics courses offer hands-on experience with circuits, ROS, Lidar, and more. Robots are everywhere, from the assembly line of major factories to the vacuums cleaning the living room ...

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 ...

If you're developing a wrist watch, a small light-following robot, or a portable weather station with Arduino, one of the best boards you can use is the Nano, and for good reason. It's pretty compact, ...
