Yes, what you want can be achieved. However, note this: If you want the two boards to communicate with variable data across a distance, then you shouldn't use RFID. Instead use, e.g., Xbee or other wireless transmission method. Or to keep it very inexpensive ($2-3), assuming the two modules will be in line of sight from each other, you can use an infrared emitter on the sender and an infrared receiver on the receiver.
Welcome! The example sketches are the best way to start. If you do the first dozen or so official Arduino tutorials on the webpage, you should be good to go as far as required knowledge for your robot!
Im new to the Arduino platform. Im messing with the example code's on an UNO R3 . Getting to know the code step by step,i think...... My closest sort of any programming was a Tandy Color Computer III 128K, which used a language similar to PBasic, That was a long time ago. I decided to put together a 2WD Robot , AnD my daughter thought it would be "sick" if it could wander about looking for fire,deploy emergency lights,sounding an alarm . Eventually......maybe..
I am making a couple of enclosures for my two boards, which will perform different functions, but sit next to each other. I want the boxes to be attached/detached easily to each other along one face.
I've already done the Attachment half of it. For the attachment mechanism, I came up with this method, inspired by my TV remote control: - Plastic hooks/inserts on the side faces of one enclosure (male) - Cutouts/holes on the other enclosure (female). - Thus, the asymmetric hooks slide into the cutouts and then are blocked from getting out.
But now how can I modify the box design to also make it detachable? In other words: Once the hooks get into the cutouts, how can I make them come out?
On the Leonardo, I noticed that SPI is isolated to the pins on the ICSP connector.
Can these pins also be used as standard Digital I/O pins?
I don't mean with low-level C/C++ code, but rather: Are those SPI pins allowed as Digital I/O pins (or can they be enabled as such) from within the Arduino framework? If so, what are the corresponding pin numbers for them?
@Mr_Arduino, Terrific effort by you on this code, as well as answering people's questions! I see you are also adding support for the MT9D111. I'm definitely going to try the Omnivision module with this code.
Here is a suggestion: Perhaps you could take a few minutes and turn this into a standard structured Arduino-importable library (along with an example usage sketch of .INO filetype). Along with that, you could make a few lines of tutorial out of your build including the hardware connections, and put it on the first post of the thread, so that others can reproduce your setup (there will also be fewer code-troubleshooting questions that way).
Also, here's a cool video by someone in Japan who made a TFT-camera out of it (this is where I first learned about the OV7670): Not sure how they got this kind of almost real-time video from it using just the Atmega:
How much does it cost to have a PCB assembled in quantities of 10 ? For example, a board that's about similar size and complexity as an Arduino Uno.
I understand that is a low quantity, but I have a requirement to make professional-quality boards for a design I have been working on. (I have experience with hot air gun and hand-soldering, but for quality reasons, wish to source it to a assembly house, whether in US or Europe or China, etc.)
I am wondering whether options exist to do it for less than US $ 20 per board. That exact figure is probably unrealistic but I want to see how close I can get to my target.
Hmm, I think you might be right. Perhaps they use the bottom-most electrode/pad as one plate of the capacitor, and based on the capacitance measured at the various other pads, they can infer the volume of the dielectric, which I guess would be the spherical analogue of a pair of opposite-facing capacitor plates. I want to try to make one of these and see how accurate it will turn out.
