Internet radio with the ESP32
Many radio stations can be heard as a MP3 stream over the Internet. Since the microcontroller ESP32 has WLAN skills on the one hand and on the other hand with two built-in digital/analog converters can convert the digital data stream into an analog signal, it offers itself as an ideal solution. In addition, a battery power supply, an audio amplifier, two speakers, a display for the transmitter display and an input device for the transmitter setting is required. The whole thing is rounded off with a housing from the 3D printer.
