Ordered a Arduino starter kit to see if I can make some fun stuff with that alone. I can always expand!
Also saw some really awesome stuff on YouTube done with the Google Open Accessory Interface, if/when I ever get advanced enough to fiddle with that I'll be sure to make some neat stuff. (I think I have a toy Dalek around here somewhere. )
I'd go for the AVR if only for the well-supported FOSS toolchain. I think software is one place where the TI launchpads can't even hope to touch AVRs.
For starting out, the Arduino isn't a bad choice.
Starting out with AVRs could be a bit tough, especially with no prior programming knowledge.
If starting from ground zero then I would recommend something really basic, PICAXE or Arduino. PICAXE has a basic syntax, makes sense. For example I wrote a PICAXE program when I was 8, its a nice language.
I then moved to the arduino because of the huge community behind it.
The Arduino is just a fancy IDE and bootloader for the same chip, and the whole mess uses the same exact same toolchain. So when I say "AVR is awesome", Arduino is generally awesome by extension.
He should've increased the voltage until it burst into flames, just like that vacuum cleaner
Also, look what someone made:
It basically let's you convert an arduino sketch into a soundfile and program it with that.
I need some help. I ordered a Usbasp for my arduino which I somehow bricked. The problem is that the wire from the programmer has 2x5 pins. The arduino only has 2x3 pins. What do I do?
You can make an adapter.
You can buy adapter cables aswell, or make your own out of shrouded headers. Sparkfun for example is selling these. Also ebay.
I figured I would ask here as well. I am having problems re-burning the bootloader on my arduino with an atmega328p. What I did (being the impatent cheapskate I am) was I soldiered some wires to the underside of the ISCP pins on the arduino. I then plugged them (correctly) into the corresponding pins on the 2x5 cable. When I plug it in (the programmer into the usb port that is) it lights up yellow, and the ON light goes on on the arduino. Using the arduino IDE I try to burn the bootloader. It tells me the board does not respond
I tried another program called eXtreme burner recomended by the site that hosts the drivers for UsbASP. It manages to get some lights to flash (a green one on the usb piece and the 'L' led on the arduino) but it errors sayingCode:avrdude: stk500_getsync(): not in sync: resp=0x00
What do I do?Code:Power on failed... Cannot communicate with target chip!
(chip is used (as opposed to new))
So, with pcb-pool.com, you can get 100 pcbs, 10mm x 10mm for 44€ + shipping. That's pretty interesting!
What are you going to fit on a 10mm^2 board?
You don't seem to understand how small 1x1cm is, you would never be able fit an arduino clone or anything of real use on it.
If you want a PCB the only real option is to do it yourself unless you happen to be rich or are doing a large batch.
I'd just gotten a ethernet shield for my birthday and I just remembered I only had only ethernet cord to my room. Dangit. I'll have to figure something out.
I decided to continue with the creation of my own psu! Today I added the switches you can see.
The top row are On-Off-On switches for selecting power output and which voltage to display on the voltmeter, and the bottom row is an On-On switch for selecting input polarity (a protective diode is of course included)
I'm going to make a wireless power prototype sorta like this.
I was wondering whats the difference between using a sine wave for this and a square wave?
I would really want to use a square wave because how easy it is to make , but maybe sine wave is more efficient?
Ok, I'm in a design class an we were issued auduino due's for our base project. We'll be interfacing it to LCD displays and stepper motors for the class, and I have to come up with an idea for a term project using the device as well as a selection of external sensor chips and devices. I have a few ideas milling about in my mind but any suggestions for a fun and interesting project are welcome.
I had a chat with some of the lab advisors and I managed to get ActiveRobotics off of them... the result: controlling a CRS-F3 robot arm with an xbox controller. I'll probably have a video soon, the movements aren't that smooth yet but it's fun to play with.
Also, does anyone know of any good indoor positioning systems? The only ones I was able to find were Active Bat and Cricket, and both of those are harder to get than the holy grail.
Screw perfboards! Freeform soldering is the way to go!
ok i have an UNO board, and im looking to get into some more advanced stuff, what is this AVR i keep seeing people post about and were would i start with one?
