This circuit is a very simple voltage monitoring device for +5V VCC supply lines. It can be used to monitor the power supply of a microcontroller (uC) by indicating when the supply level raises above ...

The Raspberry Pi 5 used this time was sent directly to the GIGAZINE editorial department from the Raspberry Pi Foundation and has not received technical standards compliance certification. Therefore, ...

In this video, I walk you through the step-by-step repair of a faulty 5V power supply. From diagnostics to replacing components, this guide covers everything you need to bring your power supply back ...

This circuit is a small +5V power supply, which is useful when experimenting with digital electronics. Small inexpensive wall transformers with variable output voltage are available from any ...

If you're developing a wrist watch, a small light-following robot, or a portable weather station with Arduino, one of the best boards you can use is the Nano, and for good reason. It's pretty compact, ...

If your introduction to digital electronics came more years ago than you’d care to mention, the chances are you did so with 5V TTL logic. Above 2V but usually pretty close to 5V is a logic 1, below ...
