ServoPiezo
The aim of this module is to interface the transducer and the servo, aka the physical parts, to the analog part of the modules chain. More to come with the Loftus head.

- Simple to use
- Slow sweeping
- Need to find a servo which frequency is above 100hz (100hz -> 10ms period -> 1 line per 10ms is quite close)
Removing the noise?
- Remove the jitter (see image in Rdme)
- Include notes
- Get a 3.5MHz piezo

The echOmods project and its prototypes (so Cletus) are open hardware, and working with open-hardware components.
