i couldnt find the book with the info i needed..... the one with the info has not been returned to the library...
and i need this circuit as soon as possible...
that's y i asked here...
sorry guys....
i really need ur help.... -
do i need to remove all the 6.8k and 20k resistors or only the 20k resistors?
what resistor value should i use then?....or do i need to find another type of transistor...?... how about BC107? -
does this mean that the resistors that i added are correct?
can i use BC547 and connect the base BC547 to the output of the circuit with 5.6k resistor in series? -
is this circuit ok?
im also thinking about adding a relay at the output (where the lamp is)..
relay with rating should i use...?
wht else should i do to make this circuit work...?
sorry... im not tht good in logic circuits... ???
thanx

do u guys mean like this?
so i need a 1k resistor.....
ok
thank u very much u guys...

thanx audioguru for the fast reply.
but i dont understand what you are trying to say....
does it mean that i need to add other components..
what should i add...?
i dont have any clues..
im a newbie in electronics.... ???
thanx.... -
hi,
I have simulated this circuit in Multisim and it works... but when i build it did work.. I have several question about this circuit.
1) do i need to add any other component for the real circuit (hardware)
2) i already put together the circuit using SN74LS21N (AND gate), SN745LS04N (NOT gate), SN745LS32N (OR gate) .. but there is no output.
3) the output (pin 8 and 6) is high when only the Vcc and Gnd of the SN74LS21N is connected... the same happens with the OR ic.
4) do i need a different supply for the Vcc? or can i use the same 5V supply for the input and Vcc...
Thanx

I really need a program 2 simulate this circuit...... :-\
can anyone help? -
hi,
i am goin to make a report for this circuit and i need a simulation result attached..
but i cant find some of the components in my simulators..
please suggest the best simulator program..
p.s. i changed the TL081 with MC34071P
thanx -
can i use a uA741 to amplify the output of LM35DT..?
what microcontroller should i use...?
im a newbie in electronic circuits...... ???
thanx audioguru for ur fast reply -
Hi,
this is my circuit. I have several questions:
a) i dont have any output at the VOUT (2) of LM35DT. Why?
b) how can i replace the LED display with 7-segment display. What do i need to add?
c) transformer with what current rating should i use?
d) what brigde rectifier should i use?. Please tell the model number.
Thanx
