W3-Analog Output & Project 1 Sketch

First thing first. I got this little plastic box with dividers inside. It is convenient for storing small jump wire segments, resistors, and LEDs used from previous labs or projects.

Project 1 Idea ad Sketch

For the first project, I want to do a project that builds a connection between the physical and digital spaces. It contains a sensor that can measure wind blowing into it, an array of LED lights, and switch to reset the program. After resting the program, the first LED will light up. Users can blow into the sensor, and the following light will turn on while the previous one goes off. The interaction is blowing the light “ball” forward. I’m currently thinking of using a microphone as the sensor and measure the volume when the user blows the wind. Larger volume means stronger wind so that the light will move forward faster. I also want to set how much force is needed to light up each LED, adding a sense of weight and resistance to each LED.
