Hi
I've designed a single side "dark detector circuit" in Orcad schematics and transfer the circuit to Orcad pcb boards,after arranging the components i tried to make auto rout, and i got a result which is not ok since i found that some tracks crossing each other but in circuit the are not...

Thanks wp100
for ur recommendation u r right,but really my target is learning how to make a pic burner and programming the pic,
if i bought a ready made pic burner then i didn't learn any thing,i just use it for programming
Thanks for all of u
Hi milan.rajik
I'm gonna make two version one parallel port and the other is serial port
which i chose from ur links "Serial Port Pro PIC-PIC18-PIC16-AVR Programmer" (the middle link),
but i really want to ask a question
what's the function of the file which u will compile?
Thanks for all of u for ur concern
,with respect to W100 post,
Thanks for attachment and I've visited the site that u refer to and went to the hardware page but i didn't find a hardware to select,but i found a circuit called "P16PRO Programmer (KIT96 & KIT119)"
is it the same as the one u...
Hi
I'm newbie in PIC programming,so I've bought a PIC16F84A and want to programmed it,I Convinced that it's easy to do it but i really found it as nightmare,
I've build many circuits depend on JDM,and ICSPP circuits and use winhex and PICPgm Programmer as programming software ,
but all my...
Hi Audioguru
I have simulated the circuit with orcad and get the bias point for Ib=24ua and 240ua with the QbreakN transistor with BF=100
and I've attached them
at Ib=24u
Ic=2.356ma
Vce=.2223 V
at Ib=240u
Ic=2.387ma
Vce=.0669V
I've noted that
at Ib=24ua Vce=.2V(then it's...
Special thanks to "BrunoARG" for its description,
but what u mean by the quoted text above?
if i had transistor as switch and the load resistance for example =5k Ohm,Beta=100 and Vcc=12V (ignore Rce)
it supposed that
at Ib=0 the transistor is in cutoff
at Ib=24 uA the transistor is fully...
Hello for all
yes i was mistaken it's 420 m Ohm and not 420 Ohm
and thanks for your help,
I've read all ur comments in hurry,but i promise to read it once again later,and if there any thing not understood i will ask u.
Regards
Thanks for ur help,
as i understood from ur description that
it depends on Ib and not the load,hence
i can calculate the maximum allowed load resistance from the eq "Vcc=Ic(RL+Rc)" as for the example u've give
the maximum allowed current for P2N222 is .5A at 420 ohm so if i have a 12V dc source...
Hi everybody
I'm confused about Transistor saturation current,as i know
Vcc=Vce+Ic*RL
where
Vcc:The source voltage
Vce:Collector to emitter voltage
RL:Load Resistance
and at saturation Vce=0 Volt
my confusion is,
Is saturation current depend on the load resistance "as the equation prove" ...
colin55 do u have an idea to rise up the voltage from 3.4v to 10v,
i thinking of cancelling the power supplier from the serial port which go to pin 4,5 and 14 and making external power.
with respect to ur website would u like sharing the link to it
based on your definition for vpp then it's 3.94 volt,
pls do u mean by DVM digital volt meter,
if so then my answer is yes I'm using DVM,
pls what's the default value for Vpp ?
please what's the pin number of Vpp as the data sheet of PIC16f84A tell,there's two voltages pins Vdd Pin14(+ve supply) and Vss Pin5(Ground)
any way I've measured the some voltages(without adding any thing to the circuit) with respect to Pin5(Gnd) of the pic
Vdd(Pin 14)(+V)=3.45V
MCLR(Pin...
