When the sign is powered up, the ESP32 broadcasts a local wifi network called "GenderBlender". When you connect to this network you'll be prompted to sign in to a captive portal (similar to airport or hotel wifi) - I've noticed that this tends to be easier on Android than iPhone, sometimes I had to manually open a browser and try to navigate. Once you're connected, use the displayed 90's-tastic web page to send commands to the sign!
