A computer, phone or tablet may be used to interact with the race timer by launching a web browser and entering the IP address of the Raspberry Pi. The Raspberry Pi may be connected using an ethernet cable, or to an available WiFi network. If the IP address of the Pi is not known, it may be viewed using the terminal command "ifconfig", and it can configured to a static value on the Pi desktop via the "Network Preferences." If the Pi is connected to a WiFi network, its IP address may be found in the 'Clients' list on the admin page for the network's router.
