There is a boring part of every computer introduction class that shows how a computer is made up of input, output, and processing. Maybe it wouldn’t be so boring if the input device was a nun… ...

In the video below, Kale salvages potentiometers from an old mixer, then hooks them up to a Pro Micro. This allows the Arduino to take these 12 inputs, and output them as a USB MIDI signal.

Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — ...

We’ll admit it, we’re all spoiled. A few bucks can now buy a computer that would have been the envy of everyone back in the late 1970s or early 1980s. So it’s no surprise that [kr… ...

In the Leonardo, an op-amp between the ATmega pin and the led means that loading is minimal and the pin can easily be used as an Arduino input. This buffer is missing on the Micro, which means even ...

The idea was to make a 5V 50Ω buffer, but this easily converted into a 3.3V 50Ω output despite the 5V rail by switching in three resistors (see diagram). Update: for a 10:1 attenuator for a 50Ω output ...

Using an Arduino Nano board together with a 2.2 inch UART HMI display the batteries can provide up to 60w of power output.
