Forewarned is forearmed.

Measuring the speed of a rotating object is a common requirement. Knowing the speed of table and ceiling fans, as well as kitchen appliances such as mixers and grinders, can often be useful. However, ...

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 ...

The EmotiBit photoplethysmography (PPG) device allows user-owned data collection for measures of cardiovascular activity (CVA) and electrodermal activity (EDA) in naturalistic settings. The aim of ...

In recent years, integrating smart home devices into your living space has never been simpler. They have become easier to set up with user-friendly apps and step-by-step guides, and some are ...

Obstacle sensor, based on TCRT5000, uses infrared diode and photo-receiver to detect obstacle in front of it - emitted light just reflects back to the sensor. Onboard, you'll find voltage comparator, ...

Robotics is an exciting field that combines engineering, computer science, and technology. It offers a practical, hands-on way to learn programming, electronics, and mechanical design. For beginners ...

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 ...

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 ...

Once the program is running in the robot, you can go to your phone to find the GalaxyRVR SSID defined in the program. Connect to it with the password in the program, in our case: 12345678. Now find ...
