MONITOR BERAT DAN TINGGI BADAN, SUHU TUBUH, TENSIMETER IOT BLYNK

MONITOR BERAT DAN TINGGI BADAN, SUHU TUBUH, TENSIMETER IOT BLYNK

          Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat dengan beberapa parameter yaitu berat dan tinggi badan, suhu tubuh dan tensimeter digital. kemudian hasilnya dikirim ke Blynk 2.0. untuk lebih jelasnya berikut adalah kodingnya.
