Networking with the B4

In this exciting project, we're connecting the B4 CPU to WiFi to remote program a B4. The project teaches students the foundations of web-based networking and involves WiFi, a simple web server, a web client and the interfacing between the various components and the B4.

In the end, students can upload a small program as a String to a Web Server, which interfaces with the B4 CPU that then runs the program.

Install the B4 Arduino Library and download the project code from:
