All you will need to do with the programming of the Arduino through the use of your Android phone is the OTG cable, which will replace the known USB cable, which will enable us to connect the card to the Android phone
Then you must download the application that plays the role of Arduino cc via the following link:
Once you have downloaded the application, open it and paste the code you want to try in the piece as shown in the image
Immediately after that, you can click on the indicated Thundermark to make sure there is no error in the code, and then upload it as in the image
You can also use a video that explains this annotated process in a coded and accurate way so that you can understand the explanation that I have shared with you in this post.
