dude,...
i mean a microcontrollers stuff..
i was not able to mention it...
coz wer already on this forum....
got a little background on it...
thats y im interested on it....
hoping for an augent help
Design a 4-20mA tester, similar to one described in this thread:
but instead of sinking 4-20mA test current, make it sourcing 4-20mA test current ..
(PICAXE-08M <==> PIC12F683)
Dude, you can add microcontroller to almost anything and make a project out of it. Just take your favorite hobby or activity and add a uC to it.
If I had time for an undergrad type project, I would make an alarm clock that gives you a math problem and wouldn't shut up until you give the right solution.
I am pretty sure there are several members in this forum willing to help you ..
I suggested to you a projct based on PICAXE microcontroller ( A PICAXE microcontroller is a standard Microchip PICmicro™ microcontroller with a pre-programmed BASIC interpreter ) as this is unquestionable the simplest way of starting with microcntrollers .. go google and use PICAXE as the keyword ..
The decision is yours .. so, what would you like to do???
im realy interested on it...
but it the implementation of it is feasible??
i mean do i need a lot money to implement it????
and will you promise to help me??
thx bro...
There are lots of people willing to help. But - EDABoard will not do it all for you.
I am new to EDAB but it is obvious that help is given to those who make a genuine effort to help themselves.
i was not that nice...sory..
i realy need help....coz our university is very poor...
we only fee for a 2dollar a semester...wer realy poor...
i need a help hir...
pls
u can start with a line following robot(it can be done cheaply and a lot of help is available on net too..just google line follower)..and after laying hands on it add some more features...also u can make a digital clock with alarm,day,date,time....or to go for a difficult one.try making a micromouse..i hope th8 should keep u busy

Mind you, Atmel's 8051 device is totally different from Microchip's PIC device. However, both of them are microcontrollers at the end. They both do micro stuff like the controller chip of a microwave oven's input panel, display panel of some washing machines, etc.
For development software, you may use assemble language (asm) which would be more difficult to learn but most of asm packages are free. Knowing asm is also the key to knowing hardware well.
If you use C language, you may need to invest on a C complier, depends on which mcu to use. For example, 8051 needs KEIL C complier (costs a lot), but there is also SDCC complier (free).
For PIC, there is CCS complier (US$125 or something), or hi-tech C (US$900?)...
When you have to decide which mcu / projects to work on, choose the one that would be easily available from your country. For example, getting a PIC mcu is more difficult in my place if I am getting it for just 1-2 pieces. Freight cost can be substantial if you need to get every component from overseas. If every penny counts, just visit the nearest electronic store nearby and see what they have. Most likely it would be a AT89C51 or 52, or PIC16F877, or 16F84a / 628...Compare the price, get a cheap crystal and a few resistors, and capacitors to start.
Afterwards, you may also need to prototype circuits yourself. Breadboard for simple projects. For more complicated projects, or you really want to go deep into making electronic stuff, learn using CAD software for PCB design and do chemical etch at home. Again, this won't cost you much and it can be fun, too.
Trust me, digging deep into app. notes provided by the manufacturers won't cost you much except the internet surfing cost, and you can learn a lot, really.
