When the button is pressed, the pin is pulled to LOW (GND), which the Arduino detects as a button press. The Arduino sends the current state of the button (pressed or released) to the Serial Monitor.

So we use the analog pin of the Arduino and form a potential divider with varying resistor values to complete the circuit. This way when each button is pressed a different analog voltage will be ...

To learn the concepts related to circuit programming. To understand and apply how to connect the different pins of an arduino board. To understand in which situations the different components that can ...

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. The ...

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 i… ...

This arduino UNO project introduces a Sun-tracking system project using an Arduino Uno, a servo motor, and LDRs to optimize solar panel efficiency. Hardware components, circuit connections, and ...

Power System I generally power my Arduino projects from a shield. It lets me avoid wasting power through the USB circuit, and also lets me easily put filter capacitors on to help smooth power.

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 ...
