Ethernet Webcam Display

Introduction

In modern Web Browsers, JavaScript provides exposes some amazingly powerful features. One of these is the webkitGetUserMedia function, which allows you to access a computer’s WebCam (with permission!).

In this example, we’ll use the Espruino board to serve up a webpage which accesses the WebCam and then sends a low-resolution image back to the Espruino board, which can then display it on an LED matrix.

You’ll Need

• An RGB123 matrix – I’ve used a 16×16
• A WIZnet W5500 module
• A Laptop/Tablet with a Webcam

Wiring Up

• Wire the RGB123 up as described on the RGB123 page
• Wire the WIZnet W5500 up as described on the WIZnet page
