 ## Objective
 The purpose of this device was really just an excuse for me to build a rotary encoder. But I do also want to investigate the feasibility of making a DIY wind turbine for charging things, so the data generated by this could be used to figure out a good location for that. Although wind speed is more relevant than direction.

 As previously noted, these materials are just scraps I had, exact measurements and type are not important. If you have access to a 3D printer or laser cutter and MDF, that would likely give a neater result, but you'd have to model the parts first.

 Now edit the file `pico/src/wifi_cred.h` and update the values accordingly.
