 - Wing angles (for each wing)
 - PSU current and tension

 ## Bill of Materials
 
-The system consists in two completely independent sets of wings, powered
-separately.

-A single Arduino board is used to control the entire setup. Its role is to send
-the commands to the BLDC motors ESCs. It also logs the flapping angle of each
-wing, which is measured using absolute magnetic rotary encoders.
