These guys are expecting a very high level of all round ability which is very hard to find They want a hardcore chip programmer who is also a hardcore internet programmer but the fact is both the technologies (embedded programming & web development) require mastering different abilities and the trend in IT firms is like they want a guy who is fluent in one thing like if one started with .net he is expected to have 4-5 years of experience in the same and would be hired to work on the same , atleast in the Indian market things go this way.

Even in web Development firms the guys who are into designing a website front part(The design and looks) are different from the ones who programme the back-end, so simply in this way only they have to get a fluent embedded developer and another web tech. developer to work on  for the technologies like TCP/UDP Protocols, HTTP, DHCP, DNS, 802.15.4, and 6LoWPAN Protocols.

I think that I can use it to replace a control module from a machine. I'm talking about producing this machines with the control made with this board.

You want to do PLC stuff here? yes could be done with the Arduino ,already there are some hobby CNC's moving with it.

"its an Investment" that you are going to bless your self in future for doing so,so get anyone, It's not necessary that you start with a uno/or deumilanove (deu is obsolete, but i love them) you can also start up with a mega , the learning goes in the same way no special ways you have to work.

Advantages of a Smaller UNO/duemilanove like board:

1) its small not many pin's but enough for a beginner.
2) cost is too less so if you fry it its fine not that much cost to incur to have a new chip.

Advantages of a Mega as starter:

1) The biggest one available.more than 50 GPIO's.
2) cost is high but then you get a whole lot of power like EEPROM etc

The disadvantage of Mega is that it has a SMD uC on it so once you fry it most probably you have to get a new Mega.

The small boards have no dis advantage leaving their limitations.

Best of Arduino!  smiley smiley-cool smiley-mr-green

I wasn't sure if it was 14 since the Arduino uno has 14 digital outputs.

ya plus the analog pins configured as outputs.

I am wondering what the min and max measuring range of the sensor is and how long it takes for it to be able to provide an accurate reading.

some centimetres, check out the datasheet, i tried to check the datasheet but my connection is slow so wasn't able to load it.

Will I be able to power the device and all distance sensors via USB connected to my PC?


USB port on your laptop or pc regardless of which OS you are using provides 5v @ 500 mA and the many sensors you propose to use bill put a power surge issue on your computers USB port, just connect the grounds of arduino + sensor + external battery source and power them from external power.
1132  Using Arduino / Project Guidance / Re: How to make a digital multimeter? on: March 16, 2012, 11:35:17 pm
Hi Sir, i think you have to start with a rotary switch like the fan regulators have, as the structure and functionality of a multimeter generally works with varying resistances at a particular point when a the regulator is moved, I attached the picture of example like the ones i manufacture the concept is the same i think you just need to tweak the place where the 250vac cap's are placed.

In a nutshell this has to be the starting point and then you have to think about the LCD also i read the post yesterday by "liudr" he mentioned many lcd usage trials out of those multimeter lcd working with arduino he mentioned as "very hard" so better use a HD44870 driver lcd only or if you can work that alphanumeric lcd.

How to make a digital multimeter more useful

I think this is a very innovative point to develop here as once things are being measured by Arduino the computer is already having a gateway of information then it can just input the information from the arduino within it self for all sorts of developments like integration with simulation programmes and xocillo oscillation software, so a lot of possibilities exist if development on this is taken up many of the people will forgo using the traditional multimeter's. smiley-wink

Most students break things, don't know why and don't care.

That happens but when people are there for learning then they know they have to ask someone with experience but its a fact also that numerous places are there where a beginner can be lost and burns their system and not always those numerous places can be pointed by a expert.

I would also suggest that you implement BLINK M led's  , these are LED's with virtually every existent color on earth in them and Plus the animations they provide are just outrageously staggering, i love these however a bit costly but you will love them(They have uC in them!  smiley-twist)
Have a look on them by searching simply BLINK M on google they are provided by the company THINK-M

I need to programme 4 vibration motors, with a programming chip.

to run in a counter sequence like a 24 hour clock.

Each motor representing a Hr Hr Mins Mins..

I was wondering which arduino kit would be suitable.

Arduino Uno?

you mean you need to control 4 vib.. motors with a programming chip.
go for UNO will be more than enough you just need four pin's.

they are afraid they will break something if they do it wrongly

One day they will confirm themselves that breaking things is actually more of a knowledge provider and lesson teacher.
1139  Using Arduino / Project Guidance / Re: ARDUINO HC SR04 AND SERVO MOTOR HAPTIC FEEDBACK on: March 16, 2012, 07:31:09 am
Thanks for sharing i like the idea, utilize a vibration motor , a servo motor is something not good to use here, now the problem with vibration  motor is that they are hardly available in stores freely so as such buy a old nokia and hack the same , do not get the arduino out of it just use its body and keep the vibration motor in it only and take the other stuff out then use a arduino mini or nano smd based to control sonar and vibration motor etc.

here you go in this way you do not even have to worry about encasing your project.
