Arduino 編碼第 1 部分：LED、舵機、按鈕、蜂鳴器等

Do you like to invent things?   In this class you will learn the basics of Arduino coding and how to use buttons, servos, speakers, and potentiometers to make exciting projects that light up, make sounds, and move.

The classes are taught using a blend of lecture, discussion and modeling.   I will demonstrate how to complete the wiring and coding through an Arduino simulation program called TinkerCad.  You will follow along on your own TinkerCad account or using an actual Arduino microcontroller and the Arduino IDE program.  Through a series of small challenges, you will learn the basics of coding and wiring. This course will prepare you for more advanced courses that will teach you how to use sensors and actuators to create your own inventions.

This class is for beginner coders.  You do not need to have any prior coding skills.  

IMPORTANT:  If you are using an actual Arduino, you will need to have access to a computer and not just a chromebook or tablet because the Arduino IDE does NOT work on those devices.

If you don't see a time that works for you, please contact me and I will try to schedule a class meets your needs.  This class can meet once a week instead of twice a week in case that is better for you. Some sections are once a week for ten weeks and some are twice a week for five weeks.
