Membuat ETU (Engine Telegraph Unit) Menggunakan Mikrokontroller dan Bascom AVR (Interrupt serial UART) Master - Slave

Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana membuat sebuah ETU (Engine Telegraph Unit) yang biasanya difungsikan pada kapal untuk memerintahkan kepada abk kapal untuk melakukan sesuatu yang jaraknya jauh atau beda ruangan, jadi dari control room dapat memerintahkan abk yang berada pada posisinya untuk mengerjakan sesuatu sesuai dengan perintah pada ETU. disini yang dipakai hanya 3 buah push button, 3 buah led dan satu buzzer pada master, kemudian pada slave menggunakan 3 buah led, 2 push button dan satu buzzer. untuk lebih jelasnya berikut adalah komponen dan programnya.

a. Minimum Sistem ATMega

b. LED

c. Buzzer

d. Push Button

e. Cara Kerja Alat

Pertama yang harus dilakukan yaitu memilih waktu untuk pemanasannya, ada menu 10 menit dan suhu yang diinginkan 60 derajat celcius adapula yang lain tergantung pilih menu yang mana, kemudian tekan tombol start untuk memulai maka alat akan berjalan sesuai setting yang diberikan, untuk merubah setting PID maka rubahlah nilai pada Kp, Ki dan Kd disesuaikan dengan plan yang dibuat. jika alat telah selesai maka buzzer akan berbunyi dan heater akan off.

Membuat Alat Mesin Antrian Menggunakan ARDUINO dan Printer Thermal + RTC DS3231 + LED Panel DMD P10 Counter Up

Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang berjudul "MESIN ANTRIAN BERBASIS ARDUINO". alat ini menggunakan led panel dmd p10 sebagai interface angka kemudian terdapat printer thermal untuk mencetak kertas antriannya, alat ini dilengkapi dengan RTC DS1307 atau DS3231. untuk lebih jelasnya berikut adalah komponen dan programnya.

c. Cara Menjalankan Program

1. Input nilai pada text box yang tersedia

2. Tekan tombol start untuk memulai

3. Jika ingin melihat deskripsi grafik maka cek list pada "legend"

4. Jika ingin merubah jenis grafik maka pilih pada combo box

5. Jika ingin close tekan tombol close pada pojok atas

ARDUINO Monitoring 5 SUHU Thermocouple Tipe K DATALOGGER EEPROM (Multiple Sensor)

Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang berfungsi untuk memonitor suhu menggunakan sensor thermocouple sebanyak 5 buah dan dimonitoring secara bersamaan. alat ini menggunakan sistem penyimpanan EEPROM sebagai dataloggernya dan juga terdapat tombol konversi yang dapat merubah dari celsius ke reamur ataupun ke kelvin atau fahrenheit. untuk lebih jelasnya berikut adalah komponen dan programnya,

a. Arduino Uno

b. Sensor Thermocouple Tipe K (5 pcs)

c. LCD + I2C

d. Program Arduino IDE

e. Cara Menjalankan Alat

Cara menjalankan alat ini yang pertama yaitu hubungkan alat dengan power supply atau adaptor kemudian pastikan semua komponen sudah terpasang secara tepat, untuk pin arduino yang terhubung ke sensor bisa dilihat pada program di bagian atas. selanjutnya tekan tombol untuk konversi, simpan data ke EEPROM dan baca data yang ada di EEPROM.
