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.

Hi Sir Robert i think he's talking about Alphanumeric LCD's which also works like below as he showed in his very first post :

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.
1131  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.

yes it seems have a look at an extensive post here --> http://hunt.net.nz/users/darran/

There has been somedays when a new project with same Magnetic Levitation was done at our arduino forum (look out for it in exhibitions) the guy had a really nice working PID for magnetic levitation , IM attaching that programme.

When the arduino then is a actual HID device, will i still be able to send serial data as before ?? Or is there a different comm protocol to use then ??

you mean that while you are using it as the HID device you can simultaneously  access the serial port as well?

Huh.  I guess you're right

Definitely this is a fact no guessing smiley , you can easily get tutorials on the web modifying a Nokia mobile interface cable to make usb to serial adapter.   smiley-wink

but isn't icsp header on the usb/serial adapter for (re)programming the ATMega8U on the Adapter?

Ya you are right , that fact got off my mind, its just this that when problems occur mind tries to look for every possible alternative and sometimes its out of feasibility.

i also see a ICSP header(6 pin) just solder it and put in 6 male headers, it can be the circuitry is fine at ICSP and gives you 5v.
1138  Using Arduino / Installation & Troubleshooting / Re: IDE not working on: March 15, 2012, 02:12:54 pm
I have seen this problem many times , so many that i can;t even count but this problem have been rather SO very Temporary as just closing all the other windows of the arduino IDE and restarting simply by double clicking the arduino.exe is sufficient maximum you have to restart your computer.

This problem more or less happens due to non-recognition of the Serial port Driver so roll back the driver once and again  install the driver afresh and then restart your IDE again.

also, have you anytime faced the Lauch4j error in IDE?, see there is no actual installation of files ,Arduino is just a static application that just sits on your hardrive and in order to work it calls from all files that makes it work, so also make sure you have completely and successfully unziped the downloaded Arduino IDE zip file.

It's working Vice-Versa, Traditionally uC's need high power to get into programming mode like PIC's (well without bootloader)  but this is programming at 3.3v and vomiting at 5v that's strange ,ok so which one USB to Serial Adapter are you using?

DFRobot,The Chinese--- must be their another quest to build that Ultra Cheap stuff , i have experienced their things failing in just 10-15 days of working even in case of high priced things, I recently bought a UNIVERSAL LIPO charger and it never charged anything any battery and it claims to be Universal.
