Imagine if restrictions spread to micro-controllers, sensors and output devices merely because of the potential that someone might devise a dastardly use for them.ctdahlehttps://www.blogger.com/profile/03301494095196099233noreply@blogger.comtag:blogger.com,1999:blog-2322291048042453151.post-61230053805148069832011-09-16T22:00:38.462-07:002011-09-16T22:00:38.462-07:00Kev, The difference in price between a "genui...Kev, The difference in price between a "genuine Arduino" UNO and the clones is so little, that it is really probably worth it to just spend a couple of extra dollars and buy the genuine article. At least for your first board. Think of it as paying back the people who put the blood, sweat, and tears into getting the entire Arduino project off the ground.<br /><br />Many of the clones are EXACT copies of the Arduino and will work exactly the same.<br /><br />But others are stripped down versions that have a slightly different form, or leave out ICSP headers, or USB, or some other portion. These are for people who are well practiced with the board and able to knowingly trade off capabilities they do not need for a specific project for a few buck's savings.<br /><br />As you gain more experience, eventually you just build your own support circuitry around the Atmel chip and skip the Arduino board.<br /><br />But for getting started, I think it is well worth your while to buy a genuine Arduino, and better yet, one of the starter kits from Sparkfun http://www.sparkfun.com/products/10173 , Makershed http://www.makershed.com/ProductDetails.asp?ProductCode=MSGSA , or Adafruit http://www.adafruit.com/products/170 All of these kits will get you up and running and well down the road to understanding Arduino.ctdahlehttps://www.blogger.com/profile/03301494095196099233noreply@blogger.comtag:blogger.com,1999:blog-2322291048042453151.post-41288832316179680492011-09-16T02:33:39.034-07:002011-09-16T02:33:39.034-07:00Hi, I'm looking to start learning about micro ...Hi, I'm looking to start learning about micro controllers and I've heard Arduino is the place to begin, I've done a little C in the past but what I want to know is should I go for an <a href="http://proto-pic.co.uk/arduino-uno/" rel="nofollow">Arduino Uno</a> or an <a href="http://www.ebay.co.uk/itm/Arduino-Duemilanove-Clone-DFRduino-Atmega-328-/130566103654?pt=UK_ToysGames_RadioControlled_JN&hash=item1e6658a266" rel="nofollow">Arduino clone</a> I know the price isin't that much less but I a student!<br /><br />Thanks in advance.<br /><br />KevAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-2322291048042453151.post-27634142544006860532011-09-11T04:57:17.796-07:002011-09-11T04:57:17.796-07:00Hi, EJB.

"time to get back to the Arduino blog." <br /><br />I've been VERY swamped with (paying) writing work of late and just never can seem to find a big enough chunk of time to get back on a roll... I need to do it.<br /><br />Thanks for the note, and I think you've lit a fire under me to get back to it...James Floyd Kelly (Jim)https://www.blogger.com/profile/13876934942928389738noreply@blogger.comtag:blogger.com,1999:blog-2322291048042453151.post-67219365711827386762011-09-10T18:24:31.072-07:002011-09-10T18:24:31.072-07:00I'm sorry to see that this site has gone dorma...I'm sorry to see that this site has gone dormant. I'm guessing that you lost interest and moved on to new things. Still, I was hoping to follow along as you worked out the kinks. Mr. McRoberts text seems to be full of serious typos and I've had to work through all the errors myself. Too bad that APress doesn't have an an online errata page like O'reilly books (Arduino Cookbook) does. Oh well, I suppose that I'm learn more by working through the problems this way.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2322291048042453151.post-74623012617245188182011-06-30T18:26:57.864-07:002011-06-30T18:26:57.864-07:00Never mind.

I'm loving this blog! I've foll...Hello all. I'm loving this blog! I've followed along with all the projects so far and now I've progressed a little bit ahead. I'm working on project 30-line following robot-using the Adafruit motor shield too. I've modified the sketch to work with the Adafruit motor shield library and I've breadboarded it all up. Everything seems to be doing what it should be doing. The calibration routine seems to work and the DC motors change speed according to variations in light hitting the LDR's. There's just one (major) problem: The three LED's glow very feebly. They just will not put out full luminosity. I'm using pin 2 (which is one of the few output pins not used by the motor shield) to drive the three LED's. I tried using my Arduino Uno without the motor shield attached but the problem with dim LED's persisted. I've tried using just one LED, thinking that maybe I'm drawing too much current but that didn't help. I tested the UNO board just to make sure I hadn't wrecked it. Using the same Pin 2 and a simple LED flashing sketch the UNO board is capable of driving my white LED at full luminosity. This works fine so I'm certain that the problem isn't with the UNO board. It must be something with the Motor Shield Library. Does anyone know a solution? I'm now ready to assemble the line-following robot but I suspect that the dimly lit LED's just won't be adequate for the task. Maybe I'll have to give up on using the Adafruit Motor Shield and get the one used by author.

The problem I have with it is that it sort of blocks off all of the other pins of the Arduino and it is difficult to tell which of them are still available to run sensors, indicators, X-Bee radios, etc.ctdahlehttps://www.blogger.com/profile/03301494095196099233noreply@blogger.com
