arduino uno detection

Hello evry one i've got a weird issue :( i have an arduino uno R3 and it was working fine. now my computer doesn't detect it (i can't find even the com port or non identified devices in the device manager) that was when i was trying a GSM shieled with 9V 2Amp power like the datasheet says the weird thing that when i plug my arduino to the USB 3.0, the light "ON" on the board turn on, but when i plug it to USB 2.0, nothing happen. what i did: i remove evry other connection from the arduino i tried with another cable i tried other devises on my USB 2 and 3, they works fine i tried to use my arduino on another computer, same problem (i dont have another arduino to know what's making this problem) i tried to reset (with button and with jumper) -> the led L does not blink what i think the problem is: probably the problem is in the arduino not the computer maybe when i plugged the power 9V 2Amp and plug to the computer in the same time (and i dnt think it can be a problem) maybe there is a problem with the bootloader please help me, at least how can i know what it the problem, did i harm something or evrything

My Arduino works fine when the shield is not attached to it but when I attach the shield, I'm unable to upload the code; I get: avrdude: stk500_getsync(): not in sync: resp=0x00 I also tried to change my board and uploaded the code on Arduino due, then it gives: device not found on COM 8 as error Otherwise the boards are perfectly fine, they are working usually they should. Also, I'm unable to reset the board when the shield is mounted on the board The code i uploaded is simple blink code,however none of the code are uploading The shield i'm using is this , the arduino's official WiFi shield shield These are the things i have already tried but none is working : -powered up the arduino from external power supply (12 V, 1A) -removed the shield and programmed it (code loads on board ) but then mounting shield on board, the led on pin 13 cease to blink -without using the shield , arduino works as usual (like that Rx, Tx pins work and pin 13's LED and power led blinks /lit up) but with the shield stacked on board , nothing seems to work

Which arduino borad to buy?

I have some electronics and programming bg as an physics student. I read the above tutorial, the led matrix looks like a easy/cool starter project. However, i have a question, For 4 by 4 matrix, it need 4 outputs and 4 grounds. With 14 i/o pins on an arduino uno (0to13), is 7 by 7 the maximum for upscaling this design without multiplexing? Or if i can get a "shield" that add more pins to the uno? Should i just get a arduino mega with 54 I/O pins? Since it is not that expensive, Is the tutorial compatible with a mega? Actually my target build is two 15 by 15 matrix displaying identical image. Can i rig up two identical led matrix, connect both in parallel to the same board?

Using Arduino Uno with mCar Program? Answered

Makeblock is a software packaged developed around the Me Orion, which is a board that is based off of Arduino, and according to their website, is cross compatible. However, they lack any information on pinouts between the two. I'd like to make the mCar project, but don't want to purchase the Me Orion. I have everything needed, including the stepper motors, stepper motor drivers, and an Arduino Uno. However, the car_robot firmware doesn't give pin numbers- instead, it has Port1 and Port2 listed under the included pins. How do these correlate to the Arduino Uno without having a shield? Which pins do I use on the Arduino? From what I have found, the connection that the first stepper driver would connect to on the Orion consists of 10, 11, GND, V-M,SDA, and SCL. What are the last three on an Arduino Uno? Same goes for the second, except 9 and 3 is listed. And for the lifting servo, is it really just pin2? Or another way of looking at it, is how would I figure out what pins are tied to Port1 and Port2 in the script?

Arduino (uno r3) not in sync, help? Answered

So I'm pretty new to arduino. Got myself an Uno rev3, and all was well for a couple of weeks. Now however, whenever I try to upload a sketch I get an error message telling me this: avrdude: stk500_getsync(): not in sync: resp=0x00 Googling this has not solved anything. I don't think there's anything messed up with the IDE, as I get this in both arduino 1.0.1 and 1.0.2, as well as Visual micro. I tried everything I could think of. Resetting the board did nothing, neither did re-installing drivers or rebooting. The serial bounce test showed no errors, and the Rx LED blinks when I try to upload.  (If you are unaware, the bounce test means connecting Rx to Tx and opening a serial monitor. Everything you send should then be bounced back.) I'm currently thinking bootloader issues, since resetting the board does not make the pin 13 LED blink.  So, does anyone know what to do here? ------------------------------------------------------ UPDATE: I am an idiot. This whole time, I had the atmega328 plugged in backwards. It works now.

Multiple Arduino Uno I/O ports driving relay Answered

Understand that the Arduino Uno can output a maximum of 40mA each from its IO port. I used 2 IO ports each (4 in total for switching) to drive a 80mA relay. In this case, the Arduino Uno is powered by USB, which draws up to 500mA. It worked and it was left to switch for a few minutes on pulsed 10 seconds interval. However, the Uno board heats up to around 50-55 degrees centigrade. Will this damage the board?
