Hello frends.
i m facing a problem...currently i m working on an "infrared based burglar alarm" which has ic CD4538 it acts as a dual precision monostable multivibrator.bt i know that i can build this circuit on 555 also, using it as monostable multivibrator.
so i want to know what is the real...
hello frend
i m facing a problem in simulating a circuit---astable multivibrator using 555.
i m attaching the circuit diagram and the error msg in jpeg.plz someone comment on this...rectify the problem
thanx.
thanx
but i still cant able to create it..because it require some modelling
if u knew the detail process plz tell me.i m running out of time for my project.
any expert opinion will be welcomed.thanx
hello frends ,i really need ur help. i m designing an infra red based burgular alarm in ni multisim10,i found every component there but could not found this-
1)UM3561--siren sound generator--8 pin
2)IR RX1 TSOP 1738---infra red receiver--3 pin
i m not unbale to create it in multisim component...
hello frends
can any one plz help me in overcoming this problem..i m trying a to design a circuit(i have the scematic) i m using the circuit wizard software,but it cannot simulate the circuit because it has very less component database..since i m a poor student,cant afford to buy the other hi fi...
hello frend..i m new on this forum..
can any one tell which is the best software to design elctronic circuits(supports component library update) and pcb transformation with auto routing facility.
thanx
