​arduino nano plc board

​This is an arduino nano expansion board that simulates the fuctionality of a P.L.C.
The board is design to eliminate the enviroment and ground noises so the arduino can safely run your programs without unexpected resets and abdnormal behaviours.

3 floor elevator arduino project

The board was designed for an elevator project of mine. The elevator project that you can read about it at the instractables page here: ​http://www.instructables.com/id/3-floor-elevator-arduino/

The program on github

You can find the program ino file datasheets and more on github.
Just follow this link: ​https://github.com/oramafanis/3floorelevator

KEY FEATURES

-Easy arduino replacements with female pin headers
-Zero noises from the ground and the enviroment.
-No resets. No abdnormal behaviours.
-Posibility to power up the arduino circuit from seperate power supply or by usb power(recomended)
-Optoisolation for both inputs and outputs.
-Isolation for reseting the arduino with relay
-3 Ready relay outputs with N.O./COM/N.O.
-2 Trimmers connected directly to analogue inputs
-Easy din - rail mount  base
-Easy wiring via terminal blocks.
