There was a small error in the PCB:

and the new ones are:

If you have already built the PCB, then it is very simple to fix this error:
 

1. Cut the colored line (in the first 2 images). Use a screw driver of a cutter. (Remember that this image is reversed!).
2. Check that it is not connducting more.
3. Solder DIL Switches.
4. Now put the resistor (R3 here):




 
 
1. Leave some part of the pin going out, and solder the resistor.
2. Now push the rest of the pin to make it touch the pin of the DIL-Switch ( like the new connection)
3. Now solder it with the pin of the DIL-Switch.

 

I know my explanation is poor , I will soon include a drawing describing this.
