 +/* 
 +Plotter auto shutdown 01 
 + 
 +For the Openbuilds Acro pen plotter. 
 +The Gcode sender (Openbuilds Control) will send the following Gcode sequence after finishing a plot: 
 +  M8 ; close the relay 
 +  G4 P0.2 ; wait 20 MS 
 +  M9 ; open the relay 
 + 
 +The relay is connected with the arduino nano with a cable. This signal can be detected as if it were a button press 
 +When the arduino received the 'button press', it transmits a code so the remote power socket will switch off. 
 +I'm using the Bounce2 library for debouncing and the NewRemoteTransmitter library for receiving and transmitting the 433Mhz radio remote signals.
