This project demonstrates how to control an LED using a push button with an Arduino board. When the button is pressed, the LED toggles on and off. This simple circuit can be a great starting point for ...

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 ...

From a simple electronic toothbrush to complicated robotics systems, DC motors are present everywhere. In most of our previous Arduino projects, we have used these DC motors as actuators and ...
