Getting Started With Micro controllers

Hey today was the historic day when I found out about micro controllers in school and we are learning Java right now. So i have couple of questions. I want to get started with Arduino and thought i buy the UNO so what are other things i should get with my Arduino Uno e.g. like any motors , gears? and can i program with java in arduino or no and is Robot c easy to learn for arduino? Also do you know any site where i can get cheap sensors for my arduino? Also if you know any c learning programming guide i would really be interested.

:relaxed: :~ :( :|

Start with the tutorials:

The Arduino book is a good resource too (“Getting Started with Arduino”).

Here’s some doc to explain C programming if you’re used to Java:

For hardware, you’ll probably want to start with LEDs, resistors and pushbuttons. Motors take a little more interfacing because they draw more current than the Arduino can put out.

is there a standard for resister or i buy them according to my circuit

Dharav: is there a standard for resister or i buy them according to my circuit

Resistors must be selected and purchased for their resistance (ohms) and power dissapation (watts) for the specific circuit they are going to be used in.

Lefty

do we use 1/R=1/R+1/R formula for parallel and R+R=R in series to find the total resistance in these circuits

Dharav: do we use 1/R=1/R+1/R formula for parallel and R+R=R in series to find the total resistance in these circuits

I don't know which circuits you are referring to, but resistors wired in series are summed for total resistance, resistors wired in parallel are equal to the sum of the reciprocals of each resistor.

Nowadays I just use on-line calculators for such answers:

wow thx so much for the links

Dharav: I want to get started with Arduino and thought i buy the UNO so what are other things i should get with my Arduino Uno e.g. like any motors , gears?

I think they gave you good advice by telling you to start with the tutorials.

I'm learning and I'm finding out there is a lot involved in different projects so I think it is a good idea to start with the tutorials.

It is also good to have a goal and then put a plan together on paper. Then you have to know whether you have the specific steps to accomplish the goal. Until you learn to work that microcontroller, you won't know what you need but there are shields (daughterboards) and projects to accomplish your goal.

The interesting thing is that hardware is always coming and going so you might be interested in something else tomorrow.

Hi,

Just starting out this may be a good starting point: http://arduino-info.wikispaces.com/GettingStarted-Software

Some tutorials here: http://arduino-info.wikispaces.com/HOME

Some of the possibilities: Look at this and click on some devices to get an idea of how they work: http://arduino-info.wikispaces.com/BrickStarterSet
