Follow these steps to upload your sketch:
- Connect your Arduino using the USB cable.
- Choose Tools→Board→Arduino Uno to find your board in the Arduino menu.
- Choose the correct serial port for your board.
- Click the Upload button.
How do I get the code for Arduino Uno?
Use avrdude with an ISP programmer, connect it to your PC and use this command in your command prompt: avrdude -p m328p -P usb -c usbtiny -U flash:r:flash. bin:r.
How can I control Arduino without computer?
Two possibilities are:
- Use a 5V USB charger and connect using an USB cable to the Arduino board.
- Use a 7.5V to 9V DC power adapter and connect with external power jack.
How can I upload a program to Arduino?
The IDE (Integrated Development Environment) is used to write code, compile programs, and upload them to the Arduino for it to execute. The IDE can be downloaded from Arduino’s website here. I used the portable one, so all I had to do was extract it to a folder and run the executable.
How to add a servo to an Arduino project?

This short tutorial, show you the basic how arduino and servo works together. 1) Connect all jumper wire as shown in diagram. 2) Connect the signal wire from servo to digital pin 9. /* Servo Basic Understanding the basic of servo in arduino projects.
Why is my Arduino not uploading my code?
Another reason why your Arduino code is not uploading might be that your board has been running for too long and needs a break. All it needs is a push on the tiny reset button embedded in it.
