As I and others have responded in other posts by the TS, he has several options.Seems a little strange, in fact odd, to attempt to design an electronic circuit assignment without any prior knowledge or experience of the subject in question?
Unfortunately seeking a total answer here, and if it was given, would not really assist you in furthering your knowledge.I have some knowledge but i have a bad teacher and nobody in class understands her
well at least tell me what to read up on, or give me a clue or a headstartUnfortunately seeking a total answer here, and if it was given, would not really assist you in furthering your knowledge.
If you feel the present tutor is failing to provide the necessary knowledge then as already intimated, the only course is to immerse yourself in some material on logic circuits and if you come to a stumbling point then there would be help here to get you through it, but otherwise the site policy is to not solve homework questions in total, as it does nothing to further your personal knowledge on the subject.
We’ve done that. Have you researched any of our suggestions? Anything at all beyond complaining that reading what we suggest isn’t helpful? Once you’ve read the links provided to you, prove to us that you’ve read them by asking related questions that show you’re willing to do the necessary work.well at least tell me what to read up on, or give me a clue or a headstart
Okay here you goThey require an electronic decision unit to indicate which of three quiz teams presses their buttons first. The unit should include light and sound.
555 timer in monostable or astableOkay here you go View attachment 199738
Each player or contestant each have their own answer button to press with a corresponding LED as soon as the first contestant presses the button a loud tone sounds all other contestants are locked out and the contestants indicator LED lights so that it's obvious who buzzed in first. The lockout occurs because really K2 contacts operate to remove availability of a bias voltage to the gate of the other SCR's, also there are other switches for reset + 555 to set a timer in case you want to specific time in which one should answer the question. But I'm not telling.
Almost forgot there are 4 normally open momentary push button switches shown for convenience you could add an additional 4 more with the 12 volt supply
I have always had to write very detailed sequences of operation for programmers . A mechanical machine person would be offended if I included instructions to use a bolt. washer, lockwasher, and nut on each connection point, the hydraulics assemblers would be offended if I included instructions that each joint must not leak, but the programmers needed more details than that. Add "feature creep" to the list of problems they cause and it is clear why software is not always the solution.I am neither, i am simply a student struggling with electronics subject
Stick this in your filing cabinet also!I have no prior knowledge to electronics,
This circuit in post #36 will do the lock out very well, although there is probably a 120 nanosecond window after the first button press where a second one might be accepted. And the circuit is even simpler than what I had thought of, plus it requires no input conditioning. This is a really brilliant design!
That is all very well for very small simple devices, now almost all industrial controls are processor based, from the Smart Relay, PLC and CNC systems, It would be almost impossible to achieve without processing power,. So if you have any intention of creating a product with a lifetime of very long then the non-programmable logic makes a lot of sense. Also, no little glitches will wipe out the code. How can you replace a fried arduino with another one if you do not have the code to reload it???
