یکی میتونه برام برنامه ی ماشین کنترلی بسازه ؟

سلام من l298n دارم برد uno اگه میشه یکی برام برنامشو بنویسه که بتونم سرعت هم کنترل کنم ماژول بلوتوث هم دارم همه وصلا و درست کار میکنن فقط برنامه ندارم من گشتم تو یوتوب ولی نفهمیدم دقیقا پین ها به چی وصله
این الان همون چیزیه که من میخوام https://www.youtube.com/watch?v=klrDAzK0jKY&t=137s لامپ اینا مهم نیس همون موتور عقبش که قابلیت تنظیم سرعت داره برام مهمه
اینم لینک سایتش

دقیق مشخص نیست که چطوری به ال 298 وصله
