I’ve built the car alarm simulator, however the “flashing sequence” in my opinion isn’t realistic. It flashes 3X then off, then 3x ect. I want it to flash on once then off and repeat like a real car alarm. So I think I need to replace the electrolyte caps or bypass one or both? What value should the replaced caps be?
If you want to change the ‘on’-time (i.e the number of flashes) you can change the value of C2, as indicated on the diagram. Sorry, no values.
Edit: Try a 47µF , this would be enough, i tested it already.

Type fault !
Bonjour…
Après plusieurs essais , j’ai remplacé la C2 : 1 uf par une 4,7 uf et cela fonctionne impeccablement…
Voila en espérant vous avoir aidé…
Cordialement
