This week I decided to really emphasize on understanding the code and the difference between analog and physical. I realized that I lack basic knowledge in coding and I needed to research and gather my questions.

Spinning small haptic game / week 3

Questions :

1. On the video it say it is Analog. Is it pseudo analog ? ! If it is analog why do we write digitalWrite and not analogWrite

1. in Analog input why don’t we declare the pinMode ( #, INPUT ) (#, Output ) in set up and why do we do so if it is digital?
2. when do we pinMOde (#, Input ) and when pinMode(#, OUtput ) ?
3. Melody exercise.. why it is only working if we upload the pitches file to the Arduino and not the file that contains the steps ?

LAB 2

1. Question in the Code : why do we use attach and not PinMode ?

2. what is the difference between the 2 examples ?

   

it seems to me that there aren’t may changes on how the code responds…

Labs - documentation

I used a photo sensor. I tested an analogRead (A0) and I was getting results from 0 - 19 .

I adjusted the map of the frequency to go from ( 0 to 19 ) .

Here is a picture of the set up ,
