Displaying Tube Times

Why I built this

Going into my second year of Univeristy, I will need to commute everyday via the Tube. From personal experience, Apps like Google Maps and City Mapper often give times that are not entirely accurate. Upon researching why this happens, I learnt that these apps base their times on TFL given schedules making the timings prone to mistakes. As we all know TFL and delays are like two peas in a pod and so inspired by this I decided to make a more accurate, simple display board for Tube Timings at my local Tube stop.

How my design differs from more common apps

My design will utilise an Arduino Nano ESP32 board which will be capable of retrieving real time tube data from the TFL API over WiFi. This will be more accurate and dynamic (similar to the physical boards at tube stations) than apps.
