Mobil Parkir Otomatis (Self-Car Parking System) Menggunakan ANDROID dan Arduino

Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah sistem mobil yang mana mobil tersebut bisa parkir otomatis, jadi mobil bisa menuju ke parkiran dan menempatkan mobil ke halaman parkir. handphone android digunakan untuk menentukan lokasi parkir yang diinginkan. mikrokontroller yang dipakai adalah Arduino UNO dan motor driver yang digunakan untuk kendali roda adalah L298. sebagai pengaman arus dan tegangan dipakai UBEC 3A agar arus tidak masuk ke Arduino secara berlebih saat motor dc berjalan. untuk deteksi jarak saat mundur digunakan sensor jarak SRF04. terdapat sensor photodioda yang akan mendeteksi lokasi parkir 1 dan 2, jika terdeteksi garis hitam pertama, artinya disitulah tempat parkir 1, jika terdeteksi garis hitam kedua, artinya disitulah parkiran ke 2. untuk lebih jelasnya berikut adalah program dam skema lengkapnya.

MEMBUAT ALAT UKUR KADAR GULA DARAH SECARA NON-INVASIVE

Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat alat dengan menggunakan mikrokontroller untuk mengukur kadar gula darah didalam tubuh, jika biasanya untuk mengukur kadar gula darah harus menggunakan sample darah, maka alat ini didesain dengan cara non-invasive agar tidak perlu menggunakan darah lagi. alat ini berbasis pantulan atau bias cahaya sehingga yang sebenarnya dideteksi adalah intensitas cahaya yang didapat dari sumber cahaya yang melewati kulit dan pembulu darah pada jari tangan. untuk lebih jelasnya berikut adalah skema dan programnya.

f. Cara Menggunakan Alat

Pertama hubungkan servo dengan mikrokontroller, kemudian pastikan UBEC 3A terpasang untuk penurun tegangan ke 5v dari 12v DC. setelah itu pastikan sumber tegangan lebih dari 1A. setelah semua siap. hubungkan servo dengan UBEC 3A untu Vcc dan GND. port signal dihubungkan ke PortC.0. untuk sensor suhu LM35 dihubungkan ke PortA.0. lcd dihubungkan ke PORTB. jika berhasil maka servo akan berputar sesuai suhu yang terukur.
