Build an ESP32 Web Server and IR Remote

Build an ESP32 web server and IR remote

My TV remote control is corroded by leaking battery and no longer working reliably, so I decided to build my own TV remote control with an ESP32 that running as a web server and IR remote control so that I can uses my iPhone to interactive with it via web browser.

How to create an interactive transport system map with shortest path algorithm

SMRT system map

Recently I build a web application which is basically an interactive transport system map that utilise the shortest path algorithm. The web application sounds trivial but it demonstrates a practical implementation of graph data structure and shortest path algorithm that you probably studied during your Computer Science subject.
