 - [GPS](https://www.hobbytronics.co.uk/ublox-gps-neo6m) (or [this](https://thepihut.com/products/gps-module-with-enclosure?variant=27741075537))
 - [microSD breakout](https://www.hobbytronics.co.uk/microsd-card-regulated-v2)
 - DC in + USB-a power regulator (or maybe [this](https://www.adafruit.com/product/1833))
 - [microSD Card](https://smile.amazon.co.uk/SanDisk-microSDHC-Memory-Adapter-Performance/dp/B073K14CVB/) - any card that's 1GiB+ will do.
 - [Arduino Uno](https://smile.amazon.co.uk/Elegoo-Board-ATmega328P-ATMEGA16U2-Arduino/dp/B01EWOE0UU/)
 - [Breadboard](https://shop.pimoroni.com/products/solderless-breadboard-400-point)
 - Jumper cables (e.g. [a](https://thepihut.com/products/adafruit-premium-female-male-extension-jumper-wires-20-x-3), [b](https://thepihut.com/products/adafruit-premium-male-male-jumper-wires-20-x-6-150mm), and [c](https://thepihut.com/products/adafruit-premium-female-female-jumper-wires-20-x-6-150mm))
 - [Battery](https://smile.amazon.co.uk/Anker-PowerCore-Aluminum-Portable-Lipstick-Sized-Black/dp/B005QI1A8C/) - Size currently unknown - I'll need to run some tests to see how much power it uses to figure out the right battery size.
 - [Project box](https://smile.amazon.co.uk/waterproof-plastic-Enclosure-Power-junction-Grey/dp/B01JHBHNMA/) - if we can't 3D print one
 - [TPL-5111](https://www.adafruit.com/product/3573) - also available from Pimoroni

## Getting Started
Run `bash ./build setup` from the command line at the root of this repository.

### IoT Device
 - Copy `settings.custom.cpp.example` to `settings.custom.cpp` and fill in the fields there
 - Review `settings.h` to make sure it matches your setup
 - Copy the folders in `iot/libraries` to your Arduino IDE libraries folder
