아두이노로 서보모터 제어하기 글을 먼저 학습하고 옵시다. 저는 미로를 아래와 같이 제작해 주었습니다. 그리고 조이스틱을 이용해서 서보모터가 잘 작동하는지 확인을 해줄텐데요, 아래 코드를 우선 아두이노에 업로드하고, 배선을 합니다. 조이스틱으로 서보모터가 움직이는 것을 확인했으면 아래와 같이 조립해주고, 추가 구동 테스트를 진행합니다. 테스트 영상은 아래와 같습니다.
The two-way communication with the Bluetooth module, which has been delayed and delayed, has finally been completed today.

Today I want to learn how to crawl with python. Crawling is one of the ways to collect the data I want from outside. Usually, companies use internal data to analyze, but if they can’t, they have to collect the data themselves from the outside. This is the method used in that case. requests moduleThere …
I’m currently learning R programming, and I’m trying to classify Kaggle loan customers using R programming. The first analysis that can be done using raw data as it is is to estimate (predict, classify) 1 dependent variable with 3 categories using 10 input variables (independent variables, X). Here, the dependent variable (target variable, Y) is …
