Arduino

Going to build a YDM!

'Going to build a YDM'

Bit ambitious as a first project, but I have 'some' background in programing.

Right now I am a student at University of Idaho. I am taking C++ and attend the ACM meetings. ACM is a group on campus that does programing challenges and is now dabling in robotics. They recently got an Arduino board, and it is my understanding that it uses C++.

This will be my first robot, except for a semester in high school where I programed a robot to navigate a maze using only a sequence of commands.

fritsldr with arduino

hi guys.
ive been having some problem figuring out the code for a fritsldr in arduino.
so far i keep getting this error:

error: expected unqualified-id before numeric constant.:

 error: expected unqualified-id before numeric constant in function 'void loop()'

Programming an atmega with the Arduino IDE

Hi guys.

from this post (http://letsmakerobots.com/node/5593 ) by Rudolph i learned that you can program an atmega with the arudino IDE even if you haven't got an arduino board.

What i have here with me now is an atmega328, a serial programmer (precisely this one: http://www.sparkfun.com/commerce/product_info.php?products_id=14 ).

This i a robot i am working on as a part of a school project. this is the first functioning prototype, it is made useing laser cut 3mm acrylic sheet in an assembly … Read more

Arduino voltage regulator and other questions.

 Hello, I have a few questions I hope somebody or several people can answer :)

 

Need help to build a obstucle avoiding robo using GH 311RT sensors

i am having this ultrasonic  sensor

http://www.seeedstudio.com/depot/ultrasonic-ranger-gh311rt-p-73.html

http://www.sure-electronics.net/download/DC-SS014_Ver1.0_EN.pdf 

Anybody please tell me how to interface this sensor with arduino, i planning to create a obstacle avoiding robot using two dc motors and a servo with this sensor.

Please help me with programming and circuit...


Thanks,

Arduino + a doorbell's wireless modules

hello, hope you had a merry christmas, and will have a happy new year!

I found a wireless doorbell, and i would like to know it it would be possible to attach the button of the doorbell, to the TX pin on the arduino, and the receiver to the RX pin, sorta like this:

doorbell.jpg 

I think i would then be able to serial print what ever i want, and serial read it with the other arduino. say controll severall motors, even if it just has one button, would this be possible?

Xbee modules help

HI, well, the free day is arriving, so i thought i'd go to sprakfun and fill my cart.

what exactly do i need to have wireless COM betwen two microcontrolers, or PC, to micro controller, or even stand alone Xbee's?

I have these items in my cart:

This is a test platform for me entering to robotics. at the moment there is only tracked chassis,gear-box twin motors,arduino,breadboard . soon I add the  GP2D120 … Read more

Motor Controller Board

Well I've almost had 3 weeks offline and got a ton of thinking done.  The physical design is basically the same, going to use a PicAxe 14M to control four DC motors with two L293Ds. The picaxe will be optically isolated from the arduino, so if the motors, an IC or a wire shorts out and decides it doesn't want to go alone that it doesn't have the arduino as an option as a buddy in IC heaven or hell.

Noise From Motors

Hi Guys,

 Some of you may remember that I was having a difficult time getting an Arduino Motor Shield to run my 4 wheel motors on my robot Herbert.  No matter what I tried, I couldn't get it to work right so I finally decided to try a different route.  I bought two qik2s9v motor controllers from Pololu...one board for the front motors and one board for the back motors.

Qik 2s9v1 Motor Control Code

Update!  I answered my own question....I found that this motor controller has a max PWM of 127 not 255.  Once I changed that, I was okay!

 

HI Guys,

 

So the time has finally come, I had some time this weekend and started turning plans and ideas into reality. I have been researching and studying milling machine, … Read more

C328R camera and Arduino

Well I've decided to replace my 2.4 ghz wireless camera on Ardbot with this guy:

JPEG Color Camera - UART Interface

While it isn't as capable as the video camera I had planned to use, it has the advantage of having a serial interface that can communicate with the Arduino, uses 3.3v, so my hope is to be able to stream the JPEG images via XBEE to my PC.

Motors and Arduino

   Hello, is it possible to control regular small DC motors with an arduino board? If yes what limitations do I have?  can I use the PWM feature to increase decrease their speed?+

what about servos, do I need a motor driver or can I control them with just an arduino? 

   thanks!

Hello and My New Arduino Robot Project

Hi Guys,

This is my first post here although I have been lurking for a few weeks now. I am brand new to the world of robots and Arduino. I bought my first Arduino in September and I'm just starting my first robot! My robot's name is Herbert...named after H.G. Wells and kind of an homage to Star Trek....

I plan to have Herbert be a long term learning project. I'm starting with simple motor control and moving up and onward from there. Here is my first video documenting my learning about Arduino motor control using transistor circuits:

Question: Arduino vs. Illuminato?

Has anyone had any experience with the Illuminato: Genesis board? I want one, but I need it to be 100% arduino compatible (save for the bling() function). You know, me being new to this stuff and all and the slight chance I may need to copy and paste a little. ;)

 

Anyways, anyone?

Self Diagnostics?

Does anybody know if it can do self-diagnostics or know of a way to do it on the arduinos?

I hope this is the place to post this contest to within the forum. If not, just let me know.

Code Repository!

Can we get everyone who has got their code to successfully run to post their files here? Ive been looking all over the site for a central area for code, and I cannot find one. If there is one, point me in that direction, if not, lets all start posting here!

Try not to paste lines of code here, lets keep it clean. uploaded files only please!

My 1st non-breadboard circuit :)

I know..a lot of you good folks could solder before you could walk and probably sleep with a soldering iron under your pillow (hope you remember to turn it off :), so here is this guy in his 30s bragging about his first circuit. Pathetic.

However soldering is a major challenge to me and actually the main reason I didn't get started with robotics years ago. It's just not easy for my unsteady hands. So I'm very happy to declare that I just finished my 1st working non-breadboard circuit. It's a motor+servo shield for my Arduino.

R-Dev-Ino

Intoroducing R-Dev-Ino

R-Dev-Ino is a Robotic Development Arduino compatible board, easily stackable. If you want to build a more complex robot, you need to modularize it. Instead of designing specific boards for each module, I have designed a multipurpose configurable board with a small prototyping area and an I2C connector made so the boards can be stackable side by side, one on top of the other like this:
This is Ardubot, another Arduino based robot. Its base is the Sparkfun Ardubot. The brain is a Seeeduino V328 Arduino Duemilanove compatible board. Powered by a … Read more
