## heating-fan-switch
Challange: A fan has to run when the heating is powered, to improve the heat-up-time of a room.
## Hardware
- 1x Arduino nano
- 1x 100k 1% Resisitor
- 1x 100k ptc (3D Printer heatbed sensor)
- 1x N-Channel MOSFET which is full-on @5V GS-Voltage, i.E. [AO3400](http://www.aosmd.com/pdfs/datasheet/ao3400.pdf)
