Project Arduino - Tutorial Membuat Alarm dengan Arduino

Tentang Projek ini

Setelah merancang “Clock Set Date Time” dan mendengar saran dari ArduPic, saya pikir itu akan menjadi ide yang bagus dan juga berguna, tambahkan “alarm bangun.” Perubahan kecil pada kode dan menambahkan beberapa komponen: Inilah “Jam Alarm”.

Dibandingkan dengan proyek sebelumnya, saya menambahkan buzzer Piezzo, LED dioda, resistor 220 ohm, tombol dan sepertiyang dikatakan sebelumnya, saya mendengarkan saran “ArduPic” dan saya menghilangkan resistansi untuk “menarik ke bawah.”

Komponen yang Dibutuhkan

Arduino UNO
Real Time Clock
Adafruit Standard LCD – 16×2 White on Blue
SparkFun Pushbutton switch 12mm
LED (generic)
Resistor 221 ohm
Buzzer
Jumper wires (generic)

Arduino Code

Untuk menghapus resistensi “tarik ke bawah”, saya harus membuat perubahan pada kode.

Gunakan resistor pullup arduino, dan balikkan kondisi logika kode.

 pinMode(P1,INPUT_PULLUP);pinMode(P2,INPUT_PULLUP);pinMode(P3,INPUT_PULLUP);pinMode(P4,INPUT_PULLUP);if(digitalRead(P1)==LOW){menu=menu+1;

Alarm Code

Aktivasi dan penonaktifan jam alarm dikendalikan oleh tombol “P4”, baris 444 “void Alarm()”.

Untukmasuk ke pengaturan alarm, Anda harus menggunakan tombol “P3” “P2” bersama-sama, baris 81

if((digitalRead(P2)== LOW) && (digitalRead(P3)== LOW))

Ketika alarm tidak disetel, bagian bawah layar akan menampilkan “Alarm Mati” ketika alarm aktif, itu menunjukkan waktu yang telah disetel. Pada waktu yang dijadwalkan, layar berkedip, LED menyala, dan buzzer membunyikan dua nada.

Untuk mematikan alarm, Anda harus bertindak pada tombol P4, atau, setelah satu menit, itu mati sendirian. Saya memasang skema listrikdan tata letak Fritzing.
