## Electronics
## How to program it
Using a USB FTDI controller you can flash the arduino pro mini using arduino IDE selecting this parameters:
* Board: "Arduino Pro or Pro mini"
* Processor: ATmega328P 5V
* Port: your USB FTDI serial port
The programmer is connected with this connection diagram:
## History and Maintenance Book
[Jan 2023]
* Servos replacement (caused by +800k cycles operation wear) some were died other just as prevention.
* Flashed new servo operation limits
[Dec 2021]
* Fixed segment movement order and timing to avoid segment collisions
* Upgraded to tighter segment shoes to avoid segment collisions
* Died servos replacement (caused by collisions)
[~2021]
* Died servos replacement (caused by collisions)
* Glued again some servos
[Sept 2020]
* Final hardware with top case and easy programming buttons and wiring
* Installation on the Bar FIB wall, Hurra!
[Dec 2019]
* Hardware and software development with arduino
