Automated heaterbox project

[Reinsch]

Hello members,

I thought I will share my project in regards of automation of heater box. As my project car #4454 is undergoing resto-modification, all parts are reviewed and upgraded if possible.
I explain most of the details in video attached.
if you want to know prior to watching - I did standard renovation of box, but also lined it inside with silver tape to increase efficiency. On top of that I've added electric stepper motor to control air mixing flap (no more mechanical cable). Direction flaps are still based on vacuum actuators, but those are connected to air solenoids. Heart of this project is Arduino microprocessor that will be also gathering data from few temperature sensors, to achieve demanded cabin temperature (this will be set by dial knob).
For testing purposes I'm using touch screen, but vehicle control panel will have knob. More in video:
