In today’s video, I will show you how to turn water into hydrogen and oxygen to generate hho gas. In this video, I separate the water molecules, which are hydrogen and oxygen, by electrolysing water, ...

Microbial bioelectronic sensors use living bacteria that can create an electrical signal in response to the presence of a ...

In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

Both image photodetector arrays and retinas are pixelated sensors that dynamically extract various features from the visual scene—e.g., color, brightness, and contrast—before transmitting electrical ...

There have been many questions about what direction Arduino would take after being bought by Qualcomm. Now it would seem that we’re getting a clearer picture. Perhaps unsurprisingly the ...
