When you’re prototyping a new project, sometimes all you need is a switch. The folks at oomlout were tired of constantly having to rewire things, so they built a universal switch box for the … ...

This project provides an easy-to use programming API to emulate a Nintendo Switch controller using an Arduino UNO R3. The API allows sending button presses/stick movements on the emulated controller, ...

Building on the experiences of recent power-saving videos, I thought I would try as an experiment whether we could switch off the Arduino itself as well as any surrounding circuitry - and then switch ...

In this video, the author is showing how he connected $10 SainSmart 8 Channel DC 5V Relay Module to an Arduino microcontroller (You can also connect Raspberry Pi) and how how he builds an 8 channel ...

He builds a simple dead bug Arduino (which he calls an Audioino) using a handful of resistors, a pair of caps, an LED, a reset switch, and most importantly – an audio jack.

The Arduino IDE is used to write the program that will interact with your Arduino and the devices connected to it. In the Arduino world, such a program is called a sketch, which has its origin in its ...

When reed switch is opened, pin 2 of Arduino goes high with the help of the pull-up resistor R2, and the alert signal is available through the piezo-speaker PZ1 (not an active piezo-buzzer). At the ...

Digi-Key Electronics has signed a worldwide distribution agreement with LogiSwitch, makers of the Arduino-friendly NoBounce line of ICs and switches. LogiSwitch’s adaptive NoBounce technology ...

Write the programme – called ‘sketch’ in Arduino speak (you do have to add ATtiny85 capability to the standard Arduino software – easy, see SparkFun link below). Re-programme the Uno as a programmer, ...
