Hi guys,
I built a "jeopardy" game buttons, meaning the first one that press his button, his light goes up even if the second one press his button.
Schematic is like this (even if it's in French, you can understand
)
**broken link removed**
I couldn't find a 2N1711 (40 years old part?) so I used 2N2219.
Also instead of using 6V bulb I used LED, 3.2V.
I power the circuit with 3V, problem is, when I press button BP1 for instance, LED A1 light, but if I release the button, it goes off
. Second problem is if I keep BP1 press (so A1 lit), when I press BP2, A2 lit too ![Eek! :eek: :eek:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
I guess it's because the 2N2219 is not a good substitute
, what could I use instead?
TIA all!
