Arduino is a microcontroller designed for real-time hardware control with very low power use. Raspberry Pi is a full computer that runs operating systems and handles complex tasks. Arduino excels at ...

A new development board blends the classic UNO layout with built-in Wi-Fi and Bluetooth, aiming to simplify the jump from ...

What happens when students stop building for grades and start building like engineers? This competition tested more than ideas.

D0WD, a low-cost alternative to LilyGo T-Display, lets you mirror your desktop monitor over Wi-Fi with an ESP32 ...

Reverse polarity is one of the most common causes of circuit failure, from hobby projects to industrial systems. The good news is that a well-designed reverse polarity protection using MOSFET ...

Last year, Semtech released the Semtech LR2021 LoRa Plus transceiver chip, designed to address the low data-rate issue associated with LoRa, but ...

When 12-year-old Matteo Mucchetti mapped out an amusement-style attraction that he wanted to create in his family’s basement and then showed it to his older brother Nico, the high-school sophomore was ...

They're reference designs for a reason.

Finally, eco-friendly music.

Sometimes the simplest objects need some overthinking. This is exactly what [Chris Borge] realized when using his 3D scanner and finding that the included rotation table left quite a bit to be ...

Most polymers don’t mix—and that’s the point. Polymer alloys succeed by engineering the interface: use thermodynamics to predict separation, processing to sculpt morphology, and compatibilizers to ...

Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, and turning off when the sensor is released. The testing of the keys ...
