Issues with declaring and writing to arrays with Arduino

19/12/2018 · Look up the C++ union structure. It allows you to define a data type which may be stored in one format, and read out in another. I use it all the time to move floats or other data non-byte types into an array of bytes, transfer the array as bytes via serial, and read out the results as floats.
