Membuat Radio penerima FM Stereo dengan arduin. Bagi teman teman yang ingin membuat radio FM digital kali ini saya ingin sharing cara membuat dan bahan bahan yang digunakan untuk membangun radio FM digital Stereo dengan tampilan display LCD 16x2. Nah ndak perlu panjang lebar cerita langsung aja :
Bahan yanh diperlukan antara lain :
1. Modul Arduino UNO R3
2. LCD 16x2 warna terserah anda
3. 2 Push Button untuk seting radio
4. 2 LED indikator Flashing dan Alarm
5. 4 Resistor 1K
6. 2 Resistor 220 Ohm
7. Modul Tuner TEA5767
8. IC24C04 untuk menyimpan data memory
9. Kabel jumper secukupnya
Modul Arduino UNO R3
