How to build a website using svelte that controls an Arduino & Led Matrix with navigator.serial
In this video, we code a website and an Arduino that can communicate with each other directly. It uses a new API called navigator serial.
In the video, I use an Arduino UNO and Max led matrix. Let me know if you have any questions.
