This project demonstrates how to turn an LED on and off using a push button with Arduino without using a breadboard. All components are directly connected using jumper wires.

Each LED is connected to one of the Arduino's digital output pins through a 220Ω resistor. A push button is connected to each input pin and uses the internal pull-up resistor feature of the Arduino.

3D print and build an Arduino Pistol-grip Transmitter for controlling Remote Control cars. Today, we’re assembling and wiring a 3D printed Arduino-based pistol-grip radio transmitter that operates ...

Interested in audio-related projects? One of the most popular Elektor projects in 2015 was Burkhard Kainka's medium-wave AM transmitter design. Let’s revisit the creative Arduino Uno-based design.

You can read the state of a button using Arduino and a few lines of code. The actual state is shown in the Serial Monitor window as 0 or 1, 0 meaning the button is not pressed and 1 that the button is ...

The Casio SK-1 keyboard is fairly well-known in the “circuit bending” scene, where its simple internals lend themselves to modifications and tweaks to adjust the device’s output in all sorts of ...
