Hi Everyone.

I’m not sure I understand exactly how to bread board this part of the diagram @Robert93820 so kindly penned up for me.

What I tried :

  • I connected the outputs of my and gate via diodes to row 18 of my breadboard.
  • I used a 1 nano-ferret capictor to connect row 18 → 19.
  • I passed a the signal from row 19 → 20 with a simple cable.
  • I then passed row 20 → 21 with a 100k resistor.
  • I then passed row 21 to ground
  • I also passed row 21 back to row 20 with another diode to complete the loop.
  • Lastly I took a second signal from row 19 → the SET input of my SR Latch (row 22).

Using my multimeter row 18 is HIGH and row 19 is LOW. Something about my loop, or my capacitor, is preventing row 19 from going high (?).

Anything I didn’t understand about this diagram? What am I missing?
