-==== 1Bit-FullAdder ==== 
-The 1Bit-FullAdder sums 3 (//A//,//B//,//C//) inputs and outputs a //sum// bit and a //carry// bit.

-Therefore 8 relays are used. I know I can build it from 6. But for didactic reason I decided to use 8. For details see the schematic.

 +==== Status ====
 +=== 2020-06-28 ===
 +Fixed the "4-Bit Register rev2" board. The board is fully functional but has some drawbacks. You need to scratch away 8 traces on the board and solder 8 short wires on it. 
  
-=== Schematics === +The fixes for rev3 are: 
-  * //left//+  * Cs were not aligned correctly to matching relais. Nobody will see this but still, it is not as intended! Fixed in rev3 
 +  * There is a mistake at the store relays. That is why you need to scratch traces. Fixed in rev3 
 +  * Rev2 is unable to select between rising and falling edge. This is fixed in rev3 by a jumper 
 +  * B.Mask is under the LED-Indicator on the back, that is why the light is not as bright as intended. Fixed in rev3. 
 +  * Numbering of the LEDs would be helpful. Fixed in rev3.

 +=== 2020-06-18 ===
 +The PCBs for the 4Bit Register and the Logo did arrive. I assembled them successfully. I'm now waiting for the new Relays HK19F for the final test of the registers. In the Logo-PCB there was a little mistake but I succeed fixing it by scraping away two traces.
