TENSIMETER,BPM,SPO2,SUHU ARDUINO
Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang menggunakan beberapa sensor yaitu sensor tekanan MPX5050GP, sensor suhu DS18B20, sensor BPM dan SPO MAX30100/30102 dan arduino sebagai mikrokontrollernya. untuk lebih jelasnya berikut adalah koding dan komponennya.
