Arduino bringt ein Entwicklerpaket für Matter heraus. Das Bundle kombiniert Nano-Mikrocontroller, Sensoren und Lernmaterial ...

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 ...

Today we are going to create a strobe light for the tips of the wings of an rc airplane using a 555 timer (NE 555 or lm 555 IC) this circuit is very easy to make with few components and most ...

If you happen to be in the market for a small artificial sun, you may be interested to know that for about $1300, you can get a tennis-ball-sized LED array that outputs 120,000 lumens.

At first glance, it may look like [Rybitski]’s 7-segment RGB LED clock is something that’s been done before, but look past the beautiful mounting. It’s not just stylishly framed; ...

We asked experts about why our LED bulbs seem to die ahead of time. Here are the reasons they gave. Tyler has worked on, lived with and tested all types of smart home and security technology for over ...

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 ...

Tyler has worked on, lived with and tested all types of smart home and security technology for over a dozen years, explaining the latest features, privacy tricks, and top recommendations. With degrees ...
