I am sanuka welcome to my channel today. I will be teaching you how to make a simple arduino led blink circuit by the way i live in sri lanka and upload new videos every saturday. So lets get going so for this project. You need only the arduino uno board and the usb cable, which comes with it. First, we will start with the arduino uno board, get the arduino ide from the link down below in the description box. Then, after installing it you can open it. So this is what your id will look like when you open it for the first time. First, click on where the curly bracket is and hit enter, then type in pin mode. This is case sensitive, then open a bracket and type in led underscore build in comma space output. All of these should be in capital. Letters then close the bracket and put a semicolon, which is very important, then go to void loop and click and click it where the curly bracket is and hit enter. Then type in digital right and open a bracket and type in led underscore, build in and put a comma and leave a space. Then type in high. Then close. The bracket and put the semicolon then type in delay and open a bracket then type in 500 or thousand yeah ill. Put 500 quick note that it is measured in milliseconds, not seconds, then leave the semicolon then again: hit enter and type in digital right, open a bracket then type in led underscore build in comma space low, then close.

The bracket and put the semicolon then type in delay, yay 500 and close the bracket then put the simple. So now the coding is done now we have to select the board here. Click on tools, then, for the board, select, arduino uno and for the port select any available port. Now i have comfort ill select that then you can press this arrow to upload the code to the board. Now you can see my arduino board is blinking, so thats it for this video.
