Loading

To Do

• add stat about api utilisation (nb of call, etc...)

Use

Create a config.h file in main/ with values:

#pragma once

#define WIFI_SSID "YOUR_WIFI_SSID"
#define WIFI_PASSWORD "YOUR_WIFI_PASSWORD"

Functionnality

Current functionnality

• api call to get next departures for each station
• 3 state of led: OFF, ON, BLINK

To Do

• blink when in transit
• fix terminus bug: we only have departures, no arrival for end of line
• implement fading
• control led intensity/ better led control
• code refactor for resuse later with metro and/or paris
