Hey. I wanna Control a DC motor over an Arduino with a L293d. I attached a picture of the Fritzing wiring. My question is first of all. Does this work? Second : Can i run it from a 9v Battery, Can something destroy like the Arduino? (they are connected over ground) I have most of the wiring from Youtube but they used a Powersupply and i dont have one.

It will help you get the best out of the forum in the future.
-
Your OS and version can be valuable information, please include it along with extra security you are using.
-
Always list the version of the IDE you are using and the board version if applicable.
-
Use quote or add error messages as an attachment NOT a picture.
-
How to insert an image into your post. ( Thanks @sterretje )
-
Add your sketch where applicable but please use CODE TAGS ( </> )
-
Add a SCHEMATIC were needed even if it is hand drawn
-
Add working links to any specific hardware as needed (NOT links to similar items)
-
Remember that the people trying to help cannot see your problem so give as much information as you can
COMMON ISSUES
-
Ensure you have FULLY inserted the USB cables.
-
Check you have a COMMON GROUND where required. ( Thanks @Perry)
-
Where possible use USB 2.0 ports or a USB 2.0 POWERED HUB to rule out USB 3.0 issues.
-
Try other computers where possible.
-
Try other USB leads where possible.
-
You may not have the correct driver installed. CH340/341 or CP2102 or FT232 VCP Drivers - FTDI
-
There may be a problem with the board check or remove your wiring first.
-
Remove any items connected to pins 0 and 1.
COMPUTER RELATED
-
Close any other serial programs before opening the IDE.
-
Ensure you turn off any additional security / antivirus just to test.
-
There may be a problem with the PC try RESTARTING it.
-
You may be selecting the wrong COM port.
-
Avoid cloud/network based installations where possible OR ensure your Network/Cloud software is RUNNING.
-
Clear your browsers CACHE.
-
Close the IDE before using any other serial programs.
-
Preferably install IDE’s as ADMINISTRATOR or your OS equivalent
ARDUINO SPECIFIC BOARDS
-
CH340/341 based clones do not report useful information to the “get board info” button.
-
NANO (Old Types) some require you to use the OLD BOOTLOADER option.
-
NANO (ALL Types) See the specific sections lower in the forum.
-
NANO (NEW Types) Install your board CORE’s.
-
Unless using EXTERNAL PROGRAMMERS please leave the IDE selection at default “AVRISP mkII”.
-
Boards using a MICRO usb connector need a cable that is both DATA and CHARGE. Many are CHARGE ONLY.
CREATE editor install locations.
-
On macOs ~/Applications/ArduinoCreateAgent-1.1/ArduinoCreateAgent.app/Contents/MacOS/config.ini
-
On Linux ~/ArduinoCreateAgent-1.1/config.ini
-
On Windows C:\Users[your user]\AppData\Roaming\ArduinoCreateAgent-1.1

Thanks to all those who helped and added to this list.
Ok sorry im new here i thougt ive done it in the Electronics general Topic sorry
It definitely won't work without code. And the code must match the actual components and wiring so having a picture of a joystick that you're not using connected in a way that's not what you intend isn't exactly helpful.
If your 9V battery looks like the one in your picture then it is not suitable for running a motor. Not enough power. And I can't see any power at all to the Arduino.

Yes i know that i have to code this! But im a lot better in Coding than in electronics. I know how to wire my Joystick that i bought it will be the same on the Arduino only the Joystick pins will change. Which battery would you recommend me? The Arduino will be powered over usb from a Powerbank or Computer
On the L293, Vcc1 (pin 16) need a connection to the logic power supply (5V).
The L293 is feeble and wastes many volts - you'd be much better off with a MOSFET H-bridge,
but it should work so long as the power source is decent, a 9V small battery is not going to
cut it, although a NiMH rechargable version would probably just about handle one motor.
Motors need lots of current, you can't skimp on this.
