Hello friends!
I look for example code for Ardunio and a 360 ° servo for studying.
Who can help?

With thanking greetings

Hi,

Can anyone verify for me, that trying to upload a program to Arduino MEGA or maybe any Arduino, the upload stops if the code contains a constant string including !!! ?

like this small one will fail:

// Upload will never end
void setup() {
  String A = "!!!";
}

void loop() {
}

this one will finish:

// Upload will finish
void setup() {
String A = "aaa";
}

void loop() {
}

Hello guys ,
so iam new here hope its the right place and im sorry my 1st post is a question  as its my 1st project :D  

ok im doing a project of a robot driven by man with grippers

so basments needs 2 big motors i use for them those drivers

So, i've been having some trouble lately and I can't seem to find a solution on the web. I've managed to controll a brushless motor through and ESC and arduino with PWM. Nothing too dificult. What I need now is a way to controll an inversion of the motor. Like you know, changing two of the wires from the motor makes it turn the other way around.

When I started using Arduino, V0018 was the latest and greatest. Since then there have been about 7 updates and every time they update, more and more of my code fails to compile.

Since V1.0 and now V1.01 it seems the capital letter "F" cannot be used for a function name. This caused the error:
error: expected unqualified-id before 'reinterpret_cast'

I do like a lot of controllers (and I am sure there are more to come!)

On the subject of the Arduino:

What is your favorite Arduino (program / form factor) compatible board???

Mine is: The Uno32 because it is a fast Arduino and can be so much more (has a PIC 32 bit chip)! I still wish it was a 5V I/O board, but 3.3V is here to stay...

We caught our first glimpse at the new, simplified Arduino Leonardo at Maker Faire back in September of last year. At the time, we were promised a late October shipping date, but it failed to materialize. Finally, Massimo Banzi has taken the wraps off the slimmed down microcontroller and its now in stock at retailers across the web. The Leonardo sports a new pin layout, dubbed R3 (which the Uno has also been updated with), that will become standard across all Arduino boards. That's a big deal for shield makers who only have to design and manufacture an add-on once to ensure it's compatible with the entire product line. The new layout also adds some extra pins and versatility, especially in the realm of shields, which can use to the new IOREF pin to determine the voltage of the processor and thus its model. That means a shield doesn't have to be designed specifically with the new ARM-based Due in mind. The other big news is that the circuitry for converting USB to serial communication and the processor itself have been combined, which not only simplifies the design and drives down costs, but allows it to communicate directly with a computer and imitate all sorts of accessories (such as keyboards and mice). Best of all, is the price. The Leonardo, complete with headers, costs just $25 -- a good $10 less than the Uno -- while the headerless, solder-friendly version retails for $22.50. Check out the video after the break for a few more details from Massimo himself.

Arduino Leonardo finally launches with new pin layout, lower price (video) originally appeared on Engadget on Mon, 23 Jul 2012 22:27:00 EST. Please see our terms for use of feeds.

In this video Massimo explains the Arduino Leonardo, talking about its differences with Arduino UNO and playing around with its mouse & keyboard features.

If you want to have a closer look to the latest arrival in the Arduino Family click here, if you want to follow Massimo’s project click here. Arduino Leonardo comes in two different flavours: with headers and without headers.

A while back I notice the simularity between the Ultrasound/IR sensors we use on robots for object avoidance to the concept of basic RADAR. (This is more like UDAR or IRDAR). Direction and range information are what the controller uses to detect objects (RADARs basically use the same information.)

So instead of building robots for a while I decided to see how good I could make my own IRDAR. Wow! One can adjust trigger point, gain and a bunch of other factors and have a way-cool little system!

Hi there,

I have an LCD03 which i'm controlling via serial. See here: http://www.technobotsonline.com/lcd03-i2c--serial-display-32400.html
