Arduino is a tool that can make life convenient and change the way you want it with your own hands if you have a brilliant idea. It allows anyone to implement the Internet of Things world with excitement, and it is an open source development environment that is easy to learn with a large and well-equipped community. We have organized the Arduino basic course so that students can be true to their motivation of 'wanting to make what they want'. You can practice making a car rear obstacle detection sensor model one by one step by step. In each practice, you can easily understand the important basic concepts that you need to know about Arduino. I will follow those who enjoy it together. Listen to Joywins' slowly shining big stone spring basic course with strong confidence. Since each scene is carefully made, start with a cup of coffee!
