Well, if you change the transistor to an NPN and if the output device is a self contained buzzer, it'll work.wanted to know your comments on wheather this would work..
0.1 MegaOhm = 0.1 millions Ohm = 100 kOhm = 100,000 Ohm.and also ive been told to find out what the 0.10M stands for ( 10-100k )
If you don't need to boil another egg right after the first one, 2 of the diodes are a waste and the diode on the buzzer is a waste no matter.any other usefull comments would be much appreciated
No point in 3 separate and almost identical circuits.thanks for that alot of help, but im actualy making a steak timer. 3 buttons ( meaning 3 of those circuits ) each button will start a timer for a different rarity of steak.
Absolutely and then you could add: 15 minutes = "incinerated"found a decent switch.. think a 4 way rotary switch would be good enough to use?
