ESP8266Audio a Wifimulti. Je tam palcový přepínač a původní vypínač na volbu 
stanic (celkem 20, ale naprogramováno je jen 10 - je to bída tam něco 
vybrat). Potřebuje to kvalitní signál wifi (má to moc malý buffer), ale v 
pohodě lze použít druhou ESP8266 kde je wifi router/extender na dohled v 
místnosti, která signál vyčistí od kolizí a pak to jede pěkně.

StreamMP3fromHTTP je funkční kód, tohle jsem z něj udělal, jsou tam nějaké 
úpravy pro zajištění funkčnosti i v obtížných podmínkách.

upload.
