Automa'c  Door  Opener No  teeth  here  so  as  to  prevent  overturning  which  may  damage  the  motor.

The  small  gear  is  a<ached  to  a  door  knob.

A  motor  is  installed  behind  the  big  gear.

Using    an  Arduino  board,  the  remote  control  is  able  to  transmit  radio  message  to  the  main  control  board.

Behind  the  gear,  there  is  a  motor  which  is  controlled  by  the  main  board.  The  main  board  contains  an  Arduino  board  which  receives  radio  message.

As  the  big  gear  turns  one  whole  round,  the  small  gear  turns  two  rounds  which  open  the  door.
