Did you design that board, airman? Very nice! Very professional.

Very Nice! ;D

Buy 10 or more and save 10% !
I've been playing with this board a lot and its really durable. I accidentally shorted it for like 30 seconds straight and its still working fine. :P
-
cant wait to pick this up! 8)

Is there other software you can use besides the Arduino or is it the only one?

you can use straight GCC - which is plain C

Not really , I learned C from reverse engineering existing code that people wrote and seeing whats happened. I've gotten pretty darn good at C from doing that.

I'm working my way through some tutorials but trying to reverse engineer code too. Hope i can end up half as good as you guy's

So what if people want to hook up a specialized shield to it? :P

then you would just use the shield except when soldering up the shield use female headers instead of male headers. Not a big deal.

thats cool, nice and very professional!

I recommend The C Programming Language by Kernighan & Ritchie
http://www.amazon.com/Programming-Language-Prentice-Hall-Software/dp/0131103628/ref=sr_1_1?ie=UTF8&s=books&qid=1229439663&sr=1-1 (http://www.amazon.com/Programming-Language-Prentice-Hall-Software/dp/0131103628/ref=sr_1_1?ie=UTF8&s=books&qid=1229439663&sr=1-1)
It's considered the "bible" of C programming. It's short and sweet. A great reference after you've learned the language, too.
Of course, this is just general C programming. IMO, learning the microcontroller architecture and how to interface with it using C is at least as big a challenge as learning C itself.

Nice man!!!
Are u shipping @ Greece???
And how much... It may be some interest for 10 pieces around.... (depends on our on line community choice... )
-
We ship International on a lot of orders
For details just email: sales [at] CuriousInventor.com
-
I took a look at the board... It's very nice... And some details are really nice! But I have a little little comment...
Shouldn't you be able to select also the voltage from the analog port pins (I mean that the analog connector is ground, regulated and signal)
Cause if a sensor outputs more that the Vref the analog register is done..... :-\
Only this....
The board is very good and I wish you good sales!!!
-
if a sensor is powered by teh regulated power supply how would it output a signal greater than the regulated power supply?
-
It's not like that.... You see... It's Vref.... A sensor powered @ 5V by regulated can produce greater voltage than a Vref at 3V for example....
That can produce.... as datasheets say problem... And since your product targets beginners to mid users that may not notice many things....
This can generate problems....
Just to make it clean... I just try to help... I'm not here to judge you :P :P :P
It's like that The voltage at the analog converter should exist a certain lever voltage of the Vref....
Correct me if I'm wrong... But I'm lately very concerned about it... It happened that I shorted my STK600...
But in STK600 if the voltage goes down... Vref0 Vref1 reset to zero...And you have to manually raise em after reset... I didn't burn anything that far... But I only share my concern with you...
Edit: Or is it only Vref that shouldn't be more than Vcc..... x(
Best Regards and wishes,
Lefteris, Greece
-
Theres a pin labeled Vref. You just jumper it to one of the power columns on the bottom left of the board ( columns of 3.3V, 5V, Vin , Gnd )
-
I don't want to say this... I know... I just want to say... that.... Is it bad if the input voltage on a ADC channel is more than Vref???
I guess so...
The analog power port pins are power only via 5V regulated... than means that the voltage of a ADC channel may be more than Vref???
My question is... Is that bad for the micro??? If yes then... It's just a small.... well... missed detail.... But This doesn't only happen with your board....
I've seen this on many other boards.... And I ask again... Is this bad.... or it's just not a concern....
Friendly, Lefteris

I don't really understand what you are saying , but I think this will answer your concerns. There is a male header pin connected to Vref of the microcontroller. On the Roboduino you can set the Vref to be either 3.3V ,5V , or Vin by connecting a jumper wire from one of the power columns that are located on the left side of the Analog pins.

Lefteris,
Here is a quote from the ATmega168 datasheet:
ADC Voltage Reference
The reference voltage for the ADC (VREF) indicates the conversion range for the ADC. Single
ended channels that exceed VREF will result in codes close to 0x3FF. VREF can be selected as
either AVCC, internal 1.1V reference, or external AREF pin.
AVCC is connected to the ADC through a passive switch. The internal 1.1V reference is generated
from the internal bandgap reference (VBG) through an internal amplifier. In either case, the
external AREF pin is directly connected to the ADC, and the reference voltage can be made
more immune to noise by connecting a capacitor between the AREF pin and ground. VREF can
also be measured at the AREF pin with a high impedance voltmeter. Note that VREF is a high
impedance source, and only a capacitive load should be connected in a system.
If the user has a fixed voltage source connected to the AREF pin, the user may not use the other
reference voltage options in the application, as they will be shorted to the external voltage. If no
external voltage is applied to the AREF pin, the user may switch between AVCC and 1.1V as reference
selection. The first ADC conversion result after switching reference voltage source may
be inaccurate, and the user is advised to discard this result.
So nothing gets burned if voltages do not get over 5V.

Thank you.... I was very worried about this in some late projects of mine...
That's why I've been asking....
I guess it's only RTFM for me :P (for anyone who gets the acronym!!!)
Thanks again...
And I wish airman best of sales!!!! ;)

Thanks
I'll be putting up a promo code here over the weekend , probably be for 5% off
-
Congratulations! ;D
Ive just seen it at curiousinventor, and a nice price too! p.s. (whats the surface mount ic?)
-
whats the surface mount ic?
Its the FT232 , used for USB communication
-
Ordered one up to compare to the Stamps and AXON that I working with now. I have a Duemilanove that I have done nothing with, it might end up in my halloween stuff instead of my robots since it looks like roboduino will be much easier to use in that respect,..
Excellent stuff all around. I can't wait to build robot #2 with the roboduino!
-
Just ordered the Roboduino. Can't wait to build my first robot with it.
-
@dscrimager and RoBoTicS
be sure to post up pics and videos of your robots, I'll add it to the Roboduino Robots Showcase
-
as soon as I get my order in i should have the robot completed with in two days then I will post up some pictures or maybe a video
-

and I reprogrammed the blink program to a different rate just to be sure that I had the environment figured out. So far so good it looks VERY promising.

For all of you new buyers! Oh!!! ;D Forgot to say HAPPY HOLIDAYS!
I will be posting my tutorial on building this awesome peace of machinery here! All i need is a color coded chart because i cant make out the other one located here. Roboduino v1.15 - 1.16 schematic
And i am using the "Soder Wick" and for cleaning my soldering gun i am using "Oatey H-20 Water Soluable Tinning Flux" Hope that will be ok because if i cant i will wait for the other one.... HEHEHE!
I ask for a color coded one because i do not have a clue on how to solder this thing. i am a noob a this but i am a quick learner. although i no how to use it i cant really make it lol wow i feel dumb. and i am just going to ask how do i solder pins? that is a never done before in my book... well for me lol
-
@AdvsNoob
All you have to do is follow the parts list that was sent in the email
We're working on detailed instructions - but most of it is obvious where to solder.
Email me - airman00 at gmail.com , I'll give you some instructions through email.
-
Lol i got it im making the video now ^_^ wow i feel stupid... It only because i am a gangster lol.... ::)

Is curiosinventor running slow because of the holidays, because I sent out my order for the roboduino about a week and half ago. I emailed them and still nothing? Does anybody know?

Okay thanks
-
Hay i added some pics on the advsnoob site ^_^ of me building the roboduino i will add video soon

Here's Bumpy bot which my Daughter calls Ruby because of the red transparent plexi base.
Right now:
- Pololu Main Chassis
- Pololu Motor Controller
- Tamiya double gearbox and caster
- 1 bump switch
- Prop-1 used as controller - will be transplanted back into my Halloween stuff but good BasicStamp1 type module.
Warning Images are BIG:

Underside showing mechanicals and Pololu Motor controller: http://www.kentonavegraveyard.com/robots/Bumpy2.jpg (http://www.kentonavegraveyard.com/robots/Bumpy2.jpg)
Going to switch in the RoboDuino and add:
- downfacing light sensors for line-following
- accelerometer (because I have an extra)
- Sharp IR sensor - probably forward facing
- More bump switches
Eventually
- zigbee module to communicate to base station and the Octobot that I'm also building ( with AXON)

@Dscrimager
Can't wait to see it, be sure to post up pics and video
@RoBoTiCs
OK CuriousInventor is back from the holidays break, should be fine now
@Everyone ( ;D )
New demo video is up on the Roboduino page : http://www.curiousinventor.com/kits/roboduino
It shows how you can make a chaser robot using the PING sonar sensor. Also explains a bunch of the Roboduino's features.
-
They just shipped it to me hopefully it will be here soon and I like the new stuff on Curiousinventors.com
-
Cool video! Thanks!
