How does it work?:

• When the Arduino starts, we get the time from the GPS, and if this is nighttime (changeable) the LEDs will be activated.
• Leds' colors are controlled by the speed, which will be represented from 0 KMP/H (Dark Blue) to 100 KMP/H (Red). (Can be changed to MP/H)
• If this is morning time or the GPS didn't get the time yet, you can press the button and force it to be activated.
• If the interior light is working and you press the button, it turns all the lights off and saves it in the EEPROM so it won't be auto-activated next time you start the Arduino.

Requirements:

• Arduino
• GPS that supports TinyGPSPlus library
• Addressable leds (Low density is recommended)

Recommended:

• Button (To control if you want to turn off/on the light mid-drive)

Available configs:

• Leds pin
• Button pin
• Number of leds
• Timezone
• KMP/H or MP/H
• Top speed which will be displayed as red
• Night time
• Day time
• Debug mode
