Among the most commonly used functions of Smart Speakers is certainly the radio feature. But as makers, being able to create our own digital radio version gives us great satisfaction. That’s why we’re highlighting this project by Pasquale, which allows you to build a radio using a dedicated Arduino shield. The FM radio shield also…
This project was inspired by the vision of a real boat equipped with various sensors capable of measuring the depth of the seabed; we therefore thought of building an autonomous small-scale boat to perform the same tasks. This could be equipped with the necessary sensors and programmed to guide you along a desired path and…
Self-learning UHF receiver consisting of a radio receiver board with Motorola decoding and a module equipped with 8 relays operating in impulse or bistable mode. In many home automation applications and in general where it is necessary to exercise remote control by radio of multiple devices installed in the same place, the classic single…
https://youtu.be/smQBHZZrqBM In this project we convert a neat looking radio into a voice-enabled, interactive storyteller. Future, here we come! The core of the project will be Raspberry Pi. More info
A small integrated SMD gives life to an excellent portable FM stereo radio receiver which can be easily created because it does not require the production of coils or the calibration of tuned circuits. The semiconductor industry continuously churns out new integrated circuits for all application areas and also for consumers and audio; among…
Based on the chip of the Philips TEA5767, this tiny module allows to realize, with the addition of very few external components, a stereo FM radio with reception frequency from 87.6 MHz to 108 MHz .. Used in MP3 players, MP4, mobile phones, etc. 3.3V @ 11mA 76-108MHz supported 100mV audio output Stereo output…. Read…
An audio file player based on an MP3 module with FM radio, Bluetooth and remote control; a 10 V stereo output and two speakers are used for the listening. The device can even work via outlet or using two 3.7 V rechargeable lithium batteries. We all know we can find any kind of loudspeakers…
A receiving unit for UHF radio-controls, equipped with a breakout board RX and a microcontroller functioning as a decoder compatible with MM53200/3750 and HT12 codifications. Here we are once again to talk about systems for radio-controlling, which are useful in various situations where you need to remotely activate/deactivate apparatuses and utilizes and it is…
[bctt tweet=”Let’s build a receiver for FM radio with a display to show info such as radio stations, signal power and RDS messages, besides an integrated stereo amplifier with 3 W speakers.” username=”OpenElectronics”] Nowadays, many of us have a smartphone in their pocket to connect with on-demand services like Spotify, iTunes, Google Play…
In this last post of the LoRa series we will see how to use the board, so to create a network composed of addressable and safe nodes. Semtech’s SX1278 integrated circuit, on which this shield is based, allows for a sophisticated and efficient communication in the LoRa (Long Range transmission) technology. This communication is…
In a previous post, you had the opportunity to discover a new Shield for Arduino, based on Semtech’s SX1278 chip that, in view of a very limited price, allows the implementation of a radio communication for a wide range of applications: from the transmission of digital signals in OOK or FSK mode, to the…
Very interesting project of an HF/Shortwave Software Defined Transceiver radio. And it’s fully open source (software plus hardware!). We love when kickstarter lets surface such a niche, spectacular project! The Portable Software Defined Radio, or PSDR, is an Open Source, Fully stand-alone HF/Shortwave Software Defined Transceiver. It includes a Vector Network Analyzer and Antenna Analyzer as well…
