can you pleas send me a circuit diagram of melody generator using um66[not this diagram]
i wanted with a loud music!
yes
BC547 means
BC547 is an NPN transistor
yes
Hi,my name is Satish. i just got on your site and to my great surprise your site is very good. i mean it is very explicit. it leave nothing to my imagination it’s really a great site for me. i am beginner in this field and i greatly appreciate your site. well can you help me by showing me how to convert a small voltage let say 3-9v into 220v.
Thanks.
i found um3481 is nt being manufactured. is it true…. is there any other ic which can b used instead of [[um3481]]
so, um66 can be replace with BT66 ??
can anyone suggest any substitute for um66 in the above circuit?? it doesnt exist in proteas…
i am working on doorbell project . i also need loud music.Can you please send me that cirucit diagram .do i need to use same speaker as specified in ckt(wattage,resistance) or is there any substitutuion or that.
hi can we use BC107 instead of BC 547 for the same circuit?
Alternative IC for UM66? Thank you.
You can use D400 for BC547
Plz give me the circuit diagram of door bell with BT66t19l , resistance 220 ohm, bc 548
my proteus software not showing this UM66 Component how I am showing it help me
