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

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 ...

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 ...

In a world filled with high-tech robotics kits and programmable gadgets, one artist decided ...

They're reference designs for a reason.

Amino acids, the building blocks necessary for life, were previously found in samples of 4.6-billion-year-old rocks from an ...

It can be surprisingly hard to find decent analogies when you’re teaching electronics basics. The water flow analogy, for instance, is decent for explaining Ohm’s law, but it breaks down pretty soon ...

For as long as small, hidden radio transmitters have existed, people have wanted a technology to detect them. One of the more effective ways to find hidden electronics is the nonlinear junction ...

Get shared CAD, firmware, and a simple HTML interface for Sesame, helping you customize looks, motions, and power without guesswork.

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 ...
