DIY Arduino Due TEA5767 FM Radio

More mature hackers will bear in mind that a crystal established radio receiver was generally a person of the very first tasks tried.  Situations have improved, but there’s even now a little something magical about collecting invisible alerts from the air and listening to the radio on a homemade receiver. [mircemk] has introduced the strategy proper up to day by making an FM radio with an OLED exhibit, managed with a rotary encoder.

The style and design is reasonably uncomplicated, primarily based as it is on a further task that [mircemk] discovered on a Chinese site, but the establish seems very slick and would choose delight of position on any hacker’s workbench. An Arduino Thanks kinds the coronary heart of the job, controlling a TEA5767 module, an SH1106 128×64 pixel OLED exhibit and a rotary encoder. The sound sign is handed through an LM4811 headphone amplifier for personal listening, and a PAM8403 Class D audio amplifier for the crafted-in loudspeaker. The enclosure is built from PVC panels, and accented with coloured adhesive tape for model.

It is easier than at any time just before to speedily place jointly jobs like this by connecting pre-built modules and downloading code from the Web, but that doesn’t suggest it’s not a worthwhile way to increase your abilities and make some handy equipment like this 1. There are so numerous assets obtainable to us these times and standing on the shoulders of giants has often been a fantastic way to see farther.

We have shown some other radio initiatives working with Arduinos and the TEA5767 IC in the previous, these as this one particular on a tidy customized PCB, and this a person created into an aged radio situation.
