im a 3rd year ECE student and my instructor in logic circuit and switching theory required us to make a simple logic circuit. nagsearch ako sa net for ideas about the said project.. but i know di ko pedeng kopyahin yung project na yun.. i found one http://www.electronics-project-design.com/phoneinuse.htmlhelp naman po.. anung improvement ang pwede kong gawin para di nman kami (my groupnates) tawaging cheaters.  |

tulad ng simpleng intruder alarm using phototransistor?

for educational purpose lang ito ha... you will be needing a phototransistor, a laser pointer, an NPN transistor and a buzzer (or led if you want)..  |

in addition lng s circuit ni sevenstring if u want to activate the buzzer with one trigger and you wand adjustable time you can use NE555 universal timer s output ng transistor. gawin mo lng syang 1 shot then use potentiomenter s circuit ng 555 timer mo.

Why don't you make a bell buzzer system. Yung pang quiz contest. Pag nag press ng button ang isang contestant, mag bubuzzer at mag indicate kung sino ang nauna. Ma-lock-out na rin ang ibang contestants. May master switch pang reset at pang enable. Pag nag press ka ng button before na-enable, bale may ibang indicator para ma-penalize ang madayang contestant.

dapat sa logic circuit, kailangan mo ICs... kung wlang ICs yan d mo matatawag na logic circuit yan.. tinatawag nga na logic circuit yan dahi gumagamit sya ng mga gates.. and.nand..nor.or.xnor.xor...etc...

opo kuya.. yun nga po hinahanap namin.. gamit din decoders, encoders, multiplexers, demultiplexers and everything.. post pa po kayo.. kasi yung mga namention above nagawa na daw po ng mga students dati..  |

hmm... kayong mag design ng circuit nyo.. specify ka lng mga inputs at is state table mo.. considering what will be the results makukuha mo na yun.. kung alam mong mag logic circuit..

alam naman po namin.. ang problema namin wala kaming project proposal.. di namin alam kung anung project ang gagawin namin.. yun lang naman po.. di po ako nanghihingi ng design.. |

haha.. sobrang sobra nman ang hinihingi sa inyo ng teacher nyo. taga Cebu k dba ??
try mo to.. project proposal..
try an automatic gate.... alam mo ba to?

bali ang automatic gate ay isang gate na may roong mga sensors. kapag nakita nang sensor na may sasakyan eto ay mag automatic open at kapag nalampasan nya na ang sensor sa kabila ito ay mag cloclose. bali ang sensor d2 ay pwdeng photoresistor.. o pwde ring ibang sensor.. kung marunong ka pwde mo ring gamitin ang infrared na mag indicate na may sasakyang parating... o pwde ring remote control...hehe medyo mahirap ito eh... |
