Membuat Alat Kendali Suhu LM35 dengan PID Control ARDUINO

Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang digunakan untuk mengendalikan suhu suatu benda dengan output yang dipakai adalah fan PC atau motor brushless, jadi alat ini seperti kendali fan saja yang mana menggunakan PID sebagai metodenya, semakin mendekati set point maka kipas akan semakin pelan dan jika sudah sampai set point maka kipas akan berhenti, alat ini memiliki beberapa buah parameter yaitu PV yang artinya suhu realtime sekarang, SV (Set Value) artinya batas set point yang diinginkan agar mencapai steady state, HYS (histerisis) artinya batas toleransi set point, akan ada batas atas dan ada batas bawah untuk toleransi, kemudian ada ONR yaitu nilai untuk menghidupkan relay atau mematikan relay. PWM artinya nilai PID atau duty cycle yang telah dikeluarkan oleh mikrokontroller untuk mengatur kecepatan fan. untuk lebih jelasnya berikut adalah skema dan programnya.

Membuat Jam Digital Menggunakan RTC DS1302 dan OLED LCD DISPLAY

Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara mengakses OLED LCD dan RTC DS1302 secara bersamaan, aplikasi dari alat ini yaitu untuk menampilkan jam dan tanggal pada lcd oled display dan juga bisa setting alarm sesuai yang diinginkan, jadi jika jam telah masuk pada zona alarm maka led atau buzzer akan menyala sehingga akan menandakan bahwa ada peringatan. untuk lebih jelasnya berikut adalah skema dan programnya.
