A few of resistors and capacitors “condition” the audio signal. The left-hand side of the schematic includes the Arduino Uno’s ATmega328 and the components located on the Extension Shield. At the ...

Made a simple Arduino circuit with a 16*2 LCD screen and LED as outputs, 5 buttons, and 2 analog switches as controls. Calculator - does simple calculations (addition, subtraction, multiplication, ...

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… ...

In this article I will add some simple Arduino LED projects starting with basic ones like how to turn on an LED, blinking, and more. Every step will have the code, the schematic, photos of the project ...

Transmitter Section The circuit diagram is simple and easy to understand, but assembling it can be a bit challenging. Below, you can see the circuit diagram for the Smart Helmet transmitter side. Here ...

Simple arduino device used to montior temperature and light levels in a room, recording readings to an automatically created spreadsheet on Google Sheets, as well as emailing results periodically. A ...

On the hardware side, we really can’t overstate how simple this project is. A common four-digit LED display is connected up to an Arduino Nano, which is then plugged into the computer for power.

Sine wave output from the low-pass filter connected with D3. Wiring diagram Arduino sketch Now is the right time to make some key design conclusions regarding the power inverter stage. Yes, you can ...
