The secondary timer was built as a backup, for portability, and as a timer that the presenter can see on the podium. It is stored in the control room. It is controlled using a mini wireless keyboard. The keyboard can be charged using a mini-USB cable.

NB: WiFi credentials are configured in /boot/config.json and read on boot. Any changes to /etc/wpa_supplicant.conf are overwritten.
