Re: Zener creating problem
Thanks again Ianp for replying. My zeners are 1N4733 for which i checked on net & which is rated of 5.1Volts. but still its giving results which i'm unable to understand. As you said I tried please see the attachment.
Re: Zener creating problem
As u say Ianp reagrding the bias voltage please see the diagram, I'm in doubt (sorry for my bad knowledge of analog electronics, but I want to improve) . usually i have seen this type of diagram for activating a 12v relay from microcontroller output. This means i...
Re: Zener creating problem
Thanks Ianp for replying. If transisitor is not a good idea what will be the perfect method. & For a similar situation but instead of comparator here I'm using a dual opamp to calculate DC current flowing. I'm converting the current into 0-5volt output, but again the...
Zener creating problem
Thanks both of you. I clicked "helped me" for both of you.pranam77 i'm very weak in analog circuits can you please tell me the role of each resistor in your circuit & how you calculated value of each resistor. I want to learn so please help me. Thanks once again.
how to increse voltage regulator output current
i'm not sure but you can try adding power transistor by taking the idea from the circuit diagram i have attached. Just try reversing the things for Negative voltage.

Hi,
I am trying to comapre 2 signal for which i have used Comaprator which has to work on 36 volts. The circuit is working fine giving me an output either 0volts or 29 volts. But this 29 volts is required to be changed to 5 volts for interfacing this signal with Microcontroller. I...
New to DSPs
I know how to work with Microcontrollers ATMEL 89 series, PIC16F, PIC18F. I want to know where are DSP's used. If I want to learn from which one should I start & how should I start.(at present i want to learn DSP for knowledge purpose.)
circuit diagram of seven segment led display
This is idealy wrong. Emitter of the Pnp transistor should be connected to +ve supply & collector should go to common of 7-segment CA display
555 retrigable
sorry. Now i have attache the pic & the file link in proteus.
I tried removing Pin 4 from +5v & now i have connected pin4 & pin2 together. Now when i press the button it''s working fine, but the system waits for the key to be released can this be removed (the key release wait)
retrigerable 555 timer
was trying to weork with 555 Timer. I tried this example given in Proteus. The circuit is working fine. The timer run for 5.167seconds each time i press the push button. But One probelm i get is let's say the timer is running and the time passed is 2 seconds at that time...
