Do you see the tiny green LED near pin 13 blinking once per second? Arduino Course for Absolute Beginners
Theory is useless without application. The course should culminate in a real project, such as: | Project | New Skill | Component |
A program called the Arduino IDE (Integrated Development Environment) that runs on your computer. You use it to write code and "upload" it to the physical board via a USB cable. Light Theremin | analogRead() , Sensor mapping |
