Hello,
I would like to add a Pir sensor to save the lamps, and I need some help to change the prog and switch on/off the nixies clock .
currently the pir sensor is on pin 4 and sends me hight or low

thanks a lot for your help.

FirmwareVersion = “018300”;
HardwareVersion “NCS314 for HW 2.2”
6 tubes

To turn off tube You need to send 64 bit of zeros via SPI interface.
```
int nZero=0;
SPI.transfer(nZero); //16bits
SPI.transfer(nZero); //+16bits - 32bits
SPI.transfer(nZero); //+16bits - 48bits
SPI.transfer(nZero); //+16bits - 64bits
```
I think the best solution is to change the function ‘void doIndication()’ at ‘doIndication314_HW2.x.ino’ file.

Good idea! I made something similar. I used a sound meter so all hardware could be fitted in a chest. I added this function to the doIndication ino file. Looking at it now together with Gra Afch’s solution, the bitshifts are very useless 😉

Not sure what the digitalWrite does though…
```
void allNixiesOff()
{
  // This is quite simple - just put everything to NULL
  digitalWrite(LEpin, LOW);
  unsigned long Var32 = 0;
  SPI.transfer(Var32>>24);
  SPI.transfer(Var32>>16);
  SPI.transfer(Var32>>8);
  SPI.transfer(Var32);
  
  SPI.transfer(Var32>>24);
  SPI.transfer(Var32>>16);
  SPI.transfer(Var32>>8);
  SPI.transfer(Var32);

  digitalWrite(LEpin, HIGH);    
  
} 
```
