Ubidots

Ubidots adalah salah satu platform yang memberikan layanan IoT untuk perangkat kita bisa berinteraksi lewat internet.

Berikut beberapa persiapan yang perlu dilakukan untuk menggunakan Ubidots. Pada halaman ini, contoh dan panduan diperuntukan untuk mikrokontroller NodeMCU. Jika Anda menggunakan perangkat lain, Anda bisa check panduan di situs Ubidots.

1. Membuat akun di ubidots
2. Download dan install Ubidots Library.
3. Copy Ubidots token
