Some time ago i tried doing this with my original arduino uno r3. I guess i had to plug the power cables in wrong order(i think it's called reversing polarity) because my arduino stoped working. It turns on (the power diode is on) but i cannot upload any sketch on it. I'm thinking about changing the ATMega chip but, before i do that i want to be certain that it's the chip issue ,not the programmer. I have another arduino uno, and i heard that i can upload sketch with it to another uno. So my idea is, if i do this i will be able to say whether it's the programmer or the chip issue. The only problem is that i don't know how to do this and i wasn't able to find any reasonable tutorials online. Please tell me what to do.
Many Thanks,
Jan
For Anyone with the same problem. Somebody answered my question on another Stack Exchange. It is here. Also this video may be helpful. It sure was to me. Basically you need another arduino, then you need to upload a ArduinoISD sketch(which is built in Arduino IDE) to it, and connect the arduino you want to program to the working arduino(the one with uploaded Arduino ISP sketch) as in this tutorial (there is something said there about the necessity of using a condesator i will update whether it is essential when i try it).

I need to make bootloader with my code.
I discovered a github with bootloaders, but i don't know what to do with it.
My experience in use of arduino is limited by burning the default bootloader for ATmega328p
So, is there any simple way just to replace default arduino bootloader code (blinking diod) to anything else?
Certainly there is. Embedded engineers replace and/or overwrite the bootloaders all the time. Here's an article on the subject but I'll outline the basics.
Select a progamming device. There are numerous devices on the market, from very inexpensive to quite expensive, depending on what else they can do besides program a chip. You can even use another Arduino as a programmer, probably least expensive of all and readily available.
Connect the programmer to the proper programming pins. For your purposes you'll want the ISP/ICSP headers (2x3 header(s)) on the board, or 2x3 connector to an non-Arduino programmer.
Upload your code using the Arduino IDE, a utility such as AVRdude, or even Atmel Studio if you're very ambitious and want complete control.
It's not that hard if you use another Arduino as your programmer and 6 female-female jumper wires as outlined in the article.
Hi I am curious to know is it possible to write an Arduino program without the Arduino breadboard itself? Can you emulate this some how instead of the hardware?
Found another post on here which was very helpful
There are a whole slew of Arduino simulators out there, many free, and
some paid products as well.
The CodeBlocks Arduino development environment includes a free Arduino simulator, still under development but functional.
Simuino simulates the Arduino Uno and Mega pins - not a pretty-looking realistic simulator, but it works.
The Python based Arduino Simulator is another option, that plays well with the official IDE
Virtronics Simulator for Arduino looks promising, but I don't see why I would pay $14.99 for it, when I could buy one or more actual
Arduino clones for that price
Many other Arduino simulators are out there if you search, and new
ones are being announced, even crowdfunded, all the time.
I wanted to integrate a sensor to arduino uno. It may be any sensor, but I should design the drivers and libraries myself. I am a beginner to this stuff. Please could someone suggest me how to start this.
For example: I have a arduino uno and a accelerometer sensor(adxl345). How should I start integrate the sensor to arduino, what are the basics I should know before doing this and what details I should know before starting. And how do I start after having those details.
Please suggest me on this or guide me the location where I get these details.
To write Arduino libraries, here are two tutorials I recommend:
Writing a Library for Arduino
Classes Course on Cplusplus.com
Once you know how to write libraries and classes, you might want to go further.
I'm developing a spherical robotic smart toy for children with autism using Arduino, and I had the same issue as you: how can I write or use libraries to keep my code clean and make it reusable.
The first thing I did was to left the Arduino IDE because I think it lacks the basic function a real programmer needs such as error checking and code completion (you could argue that it checks your code while compiling, but I want real time error checking).
I also needed a way to compile my code without using the old avr-gcc provided by the Arduino IDE. That's where Sudar's Arduino-Makefile came as a blessing! I could write my code using my favorite text editor and compile it simply.
To help some friend with their project, I put up a Bare-Arduino-Project, with all the documentation you need to get up and running.
Of course it is just a framework to get you started, but you can configure everything to suit your need. It will work on OS X and Linux. It should work on Windows as well with some changes but I haven't tested it.
Hope it helps! :)
I am a newbiee in building robots, And through searching internet i find out that we need Raspbery pi (a computer), Romeo board (The hardware), Arduino (Development environment), ROS (Robot operating system).
But i just don't understand how are these all used, What are their individual usage. Why each of these are used for?
Can anyone explain it to me?
What should I do, From where should i start?
Thanks in advance.
This might be better suited to the Robotics forum... however, I'd recommend starting with Arduino. Very beginner-friendly, very easy to find sample code and cheap projects to start with. Also, there are many books for Arduino development that explain all the hardware compatible with it.
Also, these things aren't required for all projects. I'm not entirely sure of your sources, but cool things can be done with Arduino alone, as well as along with these other tools.
I want to be able to build my own small electronic device that just has a few buttons, and stores each keypress inside a memory.
I am a pretty experienced programmer but I have no idea where to start regarding hardware, or what to search for on google.
Please give me any info that can help me out.
Arduino boards are inexpensive and the platform is wildly popular. I buy stuff like that from sparkfun.com in the developer area down the left side of the page. At sparkfun you will also find many other similar eval boards from various vendors. I like the lillypad over the arduino pro mini only because it has the programming pins already soldered. You will want the ftdi usb serial board thing for power and programming. I am a fan of the armmite pro, which is arm based. the mbed2 is real easy when you plug it in it shows up like a thumb drive, you copy your .bin file to it and press the button and it loads the program and runs it. The blue leds give me migraines but that was solved by replacing with green leds. I have a number of the header style olimex boards, good stuff, have never used the ones with displays and buttons though. Going to other sites the ez430 msp430 is a good starting platform but no buttons which you are interested in using, the stellaris cortex-m3 based family is good I would skip the 811 board and go for maybe the 1978 or something in that range, the 811 is too easy to brick.
Most of the ones mentioned above (not the olimex boards) have sandboxes for you to play in safely (turn key development environments), but at the same time you are not locked into those environments, you can do your own thing if you like, use different toolchains, flash programmers, etc. I personally would avoid the lpcxpresso for that reason, painfully tied to both windows and their sandbox.
the sam7-h256 for example, an olimex board, is powered by the usb, and a program called sam-ba is used to load your programs into the chip. That particular board does not have buttons but boards in that family are also programmed the same way. basically one usb cable for power and programming. And like the AVR (arduino and avr butterfly are based on the avr micro) the at91sam7s is an atmel part. Atmel seems to have that edge over competitors for better documentation and support. At least my belief is that contributes to the popularity of the avr (the avrfreaks website existed before the avr butterfly and the arduino), and it certainly makes me like their arm based products.
short answer, start with http://www.sparkfun.com along the left side click on Development Tools, and there are many solutions. You want to find something like the arduino, armmite pro, mbed, that either standalone or with a ftdi based usb thing you both power the board, and have an interface for programming. There should be links on the page to websites with development tools, compilers, etc, and tools for actually doing the loading of the program on the board. I recommend trying the arm, avr, and msp430 micros, as well as different vendors (many different arm based solutions with their own pros and cons for example).
The arduino platform is a cheap and easy option.
search for arduino and netduino
What language do you program in?
Arduino uses a C like language.
Netduino uses C#.
You can get a NXT kit (yes, LEGO) and use RobotC.
I can only advice how I started:
Get a bread board and some ATMel microcontrollers (ATMega16 is perfect for beginners).
You can either buy an STK500 or you use the In-System-Programming feature, and ask someone that can build you a programmer (I recommend USBasp). When you use Linux, use AVRdude and the gccavr toolchain. Under windows, you can use the WinAVR studio.
And buy some components, like resistors, capacitors, probably a quartz crystal to make simple circuits.
That's how I started anyway.
Arduino is based on Atmel AVR, so the same Arduino or STK500 board can be programmed with AVR Studio + WinAVR combination, which is nice if you already have experience in GCC. For all additional info and tutorials take a look at http://www.avrfreaks.net
