Monitor Bpm dan SpO2 Serta Tensimeter Digital IOT Blynk 2.0

Monitor Bpm dan SpO2 Serta Tensimeter Digital IOT Blynk 2.0

         Pada kesempatan kali ini saya akan menjeleskan mengenai bagaimana cara membuat sebuah alat yang dapat memonitor Bpm dan Spo2 serta tensimeter digital dengan cloud IOT Blynk 2.0. untuk lebih jelasnya berikut adalah koding dan skemanya.
