When I was doing my FYP, I found some part of the code might confuse some beginners. I actually spent a lot of time trying to make all the things work. I hope this can help others. p.s.: some part of the code in this video are borrowed from different code posted on Youtube, I will delete this video if you think it infringes on copyrights.
