Monitor Kecepatan Angin (Wind Speed) Anemometer Interface P10 RGB HUB75 Wireless Hc-12 IOT BLYNK 2.0
Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang dapat memonitor kecepatan angin dengan interface P10 RGB hub75. mikrokontroller yang dipakai yaitu Arduino Uno pada bagian transmitter dan receiver menggunakan Arduino Wifi. untuk bisa mmonitor jarak jauh maka dipakai server Blynk 2.0. untuk lebih jelasnya berikut adalah koding dan skemanya.
