Membuat Alat Input Data Menggunakan ARDUINO KEYPAD Matrix 4x4 dan Datalogger SD Card SPIROMETER

Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat dengan menggunakan arduino untuk menginputkan data diri seperti data umur, jenis kelamin, tinggi badan dan data sensor. alat ini dilengkapi dengan datalogger berupa SD Card dengan input data menggunakan keypad matrix 4x4. untuk lebih jelasnya berikut adalah skema dan programnya.

a. Arduino Uno

b. Keypad Matrix 4x4

c. Lcd 20x4 + I2C

d. SD Card Module

e. Program Arduino IDE
