“Supplino is a Quick & Dirty PSU (Power Supply Unit) made with some widely available breakout boards, an Arduino Nano (or an Arduino Nano Every) and a graphical LCD. Power output is given by a ...

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 ...

Having a big block of hot to dump current into is a very useful thing to have if you’re testing batteries, power ... to make something more automatic: a programmable load built around an Arduino ...

[Ken] needed to supply 3.3 volts of regulated power. He started by using a linear voltage regulator but after a few calculations he discovered that 72% of what he put in was lost to heat.

The Arduino Plug and Make Kit provides a 10-minute ... while an integrated switching power supply can run on power sources up to 24 V. Arduino’s cloud-based services, ranging from free to ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...
