25 Jan 2023 0

Assalamu‘alaikum wr. wb.

Hello guys, Kembali lagi bersama Inzaghi's Blog! Jika sebelumnya sudah pernah membahas tentang Modul Dasar Arduino, sekarang waktunya melakukan Implementasi Program Aplikasi Arduino Sederhana menggunakan Tinkercad dan ESP32 melalui Arduino IDE.

Ilustrasi Praktikum Arduino dengan ESP32 dan Tinkercad

TUTORIAL CARA MENGGUNAKAN TINKERCAD

Pertama, merilah kita buka Situs Tinkercad di sini (Tinkercad.com), dan klik "Log in".

Kemudian, Masuklah menggunakan Akun Google. Setelah itu, pilihlah "Personal Accounts" untuk memilih Akun Pribadi.

Setelah itu, isilah Data Pribadi seperti Negara dan Tanggal Lahir, dan klik "Next".

Selanjutnya, klik "Continue" untuk Syarat dan Ketentuan dari Autodesk.

Anda sudah masuk ke Tampilan Dashboard dari Tinkercad. Jika ingin membuat Rangkaian Arduino, silakan klik "Create your First Circuit Design" pada Circuits.

Setelah itu, Rangkailah sesuka hati Anda. Dan inilah hasilnya setelah dijalankan :
