Description
This is an Arduino Radio .In this project i combined an Arduino nano and
TEA5767HN Radio chip(TEA5767HN is a superhetrodyne low power radio ic by
Philips) to make a Radio.we can change the frequency whith the help of
rotary encoder. tuning range is between 87.5Mhz and 108Mhz.The Audio output of the ic
is too low to drive a 4ohm speaker so i connected PAM8403 CLASS D amplifier to TEA5767HN to hear the sound clearly.
