Membuat Digital FM Dengan Arduino

Membuat Digital FM Dengan Arduino,~ Selamat berjumpa lagi di www.tempatbelajararduino.com

Kali ini kita akan membuat project membuat Radio FM dengan Arduino, Asik bukan mengenal arduino lebih dalam kita bisa mengkreasikan proyek proyek yang keren dan sederhana dengan Microcontroller Arduino ini, Oke di sini kita juga akan pake LCD 16x2 Untuk menampilkan Berbagai menu pilihan untuk menseting radionya, Baiklah saya tidak perlu panjang lebar lagi langsung saja. 

Berikut komponen yang di perlukan :

1. Modul Arduino Uno / nano/promicro
2. LCD16x2 Warna silahkan sesuka anda
3. LED indikator flashing dan alarm
4. 2 buah tombol push button untuk seting radia
5. Modul Fm tunner TEA5767
6. 4 buah rasistor 1K
7. 2 buah resistor 220 Ohm
8. Kabel jumper secukupnya
