Travel Alarm Clock (buttonless)

I recently bought a small batch of Cheap Yellow Displays (CYD) from Ali Express and have run out of interesting projects, all copied from Github and elsewhere on the internet. The CYD is a highly versatile piece of kit, ESP32 based, USB powered, 2.8-inch touchscreen LCD, Wi-Fi and Bluetooth connectivity, all at a ridiculously low cost. I/O connectivity is limited. There is also a JST connector for an external speaker. In my opinion the choice of build options is limited, especially for a relative newbie like me, unless you are into Home Assistant, IoT stuff, which seems to be where most of the applications are. Why a buttonless travel alarm? Well, (a) because I couldn’t find one for the CYD; (b) because I needed a new travel alarm, and (c) buttonless because the CYD doesn’t have a lot of options when it comes to I/O connectors. Also, Wifi scanners and weather stations I already have – they were my learning curve. There are quite a few clock calendars as well but I couldn’t find a decent alarm clock anywhere. Having already built one with a 16 x 4 LCD display I now felt that the CYD might make a good starting point for a travel alarm clock. So here goes….
