| /* Arduino data manipulation and concatenation with structures and unions | |
| * | |
| * This simple (ish) sketch shows you how to organize your data into a struct | |
| * and then access the whole thing as a byte array. | |
| * | |
| * Useful if you want to concatenate several variables into a single byte array | |
| * to send over bluetooth, i2c, lora or any other protocol that works with arrays. | |
| * In other words you have a fixed byte array, and we squeeze in variables of different | |
| * data types and lengths into it, while still using it as a byte array afterwards. | |

Instructions tested with a Raspberry Pi 2 with an 8GB memory card. Probably also works fine on a Raspberry Pi 3.
Download the latest Raspbian Jessie Light image. Earlier versions of Raspbian won't work.
Write it to a memory card using Etcher, put the memory card in the RPi and boot it up.
