Need PIC16F84A Cool Project - Electronic Circuits Projects Diagrams Free

Agent 009 · 22nd May 2005, 09:59 PM

Hey Guys!
I need a project that can be applied using the MicroChip PIC16F84A microcontroller... Any Ideas :roll:?
I've got plenty, but i need some stuff that can be done fast, and feasible... Not like cutting-edge Terminator robots :wink: ...

Try do do RS-232 to 2*16LCD interface. So when you type something in hyperterminal, it's being displayed on LCD...

Edit: And it can even serve as an Scrolling Ad.

That's good! 10x Jay! I thought of it, but the problem is like this:
My project should stand out on a piece of plexyglass (no problem until now) AND it should run independently, i mean, u just plug it to the power outlet, and it does what it does... I can't have a terminal conneted 2 it, that's bc it's gonna be put in a kinda presentation room...

BTW, nice vote, jay :wink:

Well you can have text stored in internal EEPROM + you can connect keyboard to input text (4*4 keyboard or PC keyboard)

ROFL, my vote is absolutely true! :twisted:

Euh

ops: , what's ROFL :?:
I though of a nice game:
LCD screen showing up a sequence of letters or numbers, each after another, waits a little, then clears it up for user to enter the same sequence. It starts from 2 letters, and keep incrementing to get harder and harder...
Any ideas how to implement this using the 16F84A?

an keybord,an LCD and an random generator

it randmizes 2 charecters and then keeps randmizing it and adding charters to that string.

highscores on its EEPROM wod be cool

Agent 009 · 23rd May 2005, 07:03 PM

yeah, but is the keyboard an ASCII one? Do i take a normal PC keyboard?? And what's a random generator???
I though i would realized a fake random sequence in the program...

why not try something usefull and maybe turn it into commercial product?
adding LCD is quite simple and pretty much a must nowdays.
same goes for communication. but combining them and maybe
adding another thing or two could make it a real hit. some are
already done but just think what can be done that other people
would say 'wow that's cool, i'd like to do the same':
maybe a frequency counter? maybe ODB2 interface?
maybe data logger? maybe com port sniffer that can
autodetect baud rate? maybe just a simple dialer (device that
stores list of contacts and phone numbers and can dial selected
number by generating DTMF on a press of a button)? i just hate
to se how many mobile phones come with useless junk like
stupid games etc. but who likes to type 10-digit number on some
other phone if your phone's battery is low or you are out of
coverage area? i like Jay's idea... 8)

10x Panic Mode! Nice ideas, though not really feasible in my case, cause that's a course project, and I don't need it to be much complicated...

Someone Electro · 23rd May 2005, 07:59 PM

the moe simple it is the less stuf can go wrong.

How about a Glowing Orb of Doom(TM). Get a bunch of red, yellow, and blue LEDs (possibly other colors if u want), orient them into a ball shape. Perhaps you could find a translucent ball, or maybe make your own with a membrane of some type. Put the LEDs and the microcontroller inside. You might need a bunch of LEDs going around inside to make the light look evenly distributed, and not have patches of dark and light. Have the micro turn on the LEDs in various patterns. Have the reds all on, do different intensities, turn on some yellow to make it look orange. Have yellow and blue on to make a green. Have it pulsate. Bonus points for putting a microphone inside and making light patterns 'dance' to music. 8) The whole thing could hang from the ceiling by a chain, and the power cord goes up it. That way it's floating in the middle of the room or something. I'm probably going to make one of these some time, I just need the motivation.

ZachTheTerrible: You need one of these for your car.

Someone Electro · 23rd May 2005, 08:23 PM

PWM wod make it look even beter but its an crapy F84A

Agent 009 · 23rd May 2005, 08:56 PM

Yeah, but bonxer has a gr8 idea: i think I'm gonna do an Orb after all! I found a 'wireless' Orb idea, using the 16F84A... That's bronxie 4 the motivation :wink: ... I just figured out that motivation was the missing part of my project...
Anyway, anyone still got an idea is MORE than welcome to post it.
10x buddies :wink:

Puting an ultrasonic sensor in so wen someone stares it for a wile it makes an loud beep to scare him off.Cod make an nice prank.

Some of my frends still fall in for hold this wire thingy (the wire is conected to high voltage ufcurce at low curent so i dont kill him)
