This document is aimed at the Arduino developers, radio experimenters, hobbyists and anyone interested in building a receiver based on the Si473X IC family from Silicon Labs. This project is about an ...

Arduino library for the Texas Instruments TLV320DAC3101 I2S Stereo Audio DAC. The TLV320DAC3101 chip is a low-power, highly integrated, high-performance DAC with 25 selectable digital audio processing ...

Thanks to software frameworks and libraries that have become quite powerful over time, even with a compact and inexpensive system, it is possible to achieve complex functions. In this project, we use ...

This project demonstrates an Arduino-powered wireless frequency meter that can measure the frequency of sinusoidal AC transmissions ranging from 50Hz to 3kHz. Figures 1 and 2 show prototype ...

Today, We will review the Cytron Maker Uno RP2040 development board combining the Arduino UNO form factor with the Raspberry Pi RP2040 microcontroller that makes it programmable with the Arduino IDE ...

A buzzer has two pins, namely positive and negative. The positive terminal is represented by the ‘+’ symbol and negative terminal is represented by the ‘-’ symbol just like an led and a capacitor.

SOCORAD32, aka ESP32 Software Controlled Radio, is a hackable, open-source hardware ESP32-based amateur radio board for walkie-talkie and data communication applications. The board comes with an ESP32 ...

To build an FM receiver, developers can use highly integrated chips, such as the TEA5767 from NXP. Here we describe an FM receiver with a frequency range of 76 to 108 MHz and 2 x 3 W stereo sound ...
