Week 1 Pcom

   Physical computing, to me, is a new thing. After reading the assignment and trying some labs, it reminds me of doing a circuit physics experiment back in high school. It is not the field that I am good at, but I feel inspired by the creative exercises in class that might drive me to be interested in physical computing.

  I did the lab, and in the electronic measurements measuring voltage, I kind of failed the experiment. I used the multimeter to do the test, and I think everything went through in the first part, and I measured the dc power supply. 



he label on the dc power supply shows the output should be 19v. But during my measurement, it is a volatile number changing in the multimeter. But the problem is that after putting all the voltage and led, the led can not be light up, and it shows low in the multimeter.



 Then we go back the check every step and test the voltage regulator; we find out actually after we put the DC power jack on, the power didn't go through. Still not sure what's the problem. Maybe is the DC power jack doesn't match with the one I have?

  
 


For the lab switches, I think I did better than the multimeter one. I changed my power through Arduino, and I think it went through. I followed the instruction and successfully lighted up the led. The only thing I didn't quite understand is that the different output Arduino has. 




  I go through some tutorials about Arduino, and I feel it is something more complicated than I thought and still processing what is going on. From my understanding, it is also a component, but we can be more customized about it. I wonder if the code we wrote in Arduino only changes how power goes through other parts and gets other feedback?



   I also went to the pcom workshop. I learned some basic knowledge about pcom, also have a simple idea about what I can do with pcom. In the workshop, I learned some components, and also I am very interested in many sensors. I feel like these can be significant way-to-do interactions. I would love to know more about them and how to use them and maybe combine some components to make something more exciting.

WEEK 6

 This week we learned more about the serial. From my understanding, the goal of learning it is to connect Arduino with P5.  I reviewed the slid to read more about how the transaction was down. Lab 2 Serial Input to P5.js I was having a hard time understanding all the functions.  Also, the P5 serial control is unclear to me to control. Also, I have problems understanding the orders of open Arduino, P5 serial control, and P5.  I was correct on every coding part, but my console said it is undefined. The p5 serial control can read the number, and the p5 also has the canvas drawing.  But the undefined keep shows up. So the problem very much happens on the p5 side. And I tried a lot of ways to change some code, it didn't help.  Ends up I changed my browser to chrome, and it works.  Lab3 In lab3, what confused me is which code is actually connecting p5 and Arduino? Are serial read and serial write the same? Are they connected with each other?  In lab 3, the mouse drag one; I think my LED

Week 2 Lab

  In this week's lab, I kind met some fundamental problems, so I kind can't achieve any lab successfully. I think it maybe some setting problems with my Arduino. For the first lab Digital input & output with Arduino, I think I do understand the concept that to use different pin to control the power by coding.  I do think my circuit is right, and I also tested my led are working. In the Arduino I verified my cod, everything  went through successfully. But after I upload it it saids programmer is not responding    Then I move to the lab Analog in with an Arduino. First of all I kind son't understand what dose Analog means in this content. Dose it means all the changing  parameters? In my understanding it is more like how to use different sensors working with Arduino. And in this coding I do have some hard time to understand some words. Like the const int and int, what should be const int and what should be int? And is the analogWrite and analogRead have to be appeared as

Project 2 Prototypes

 In this project, we are trying to make a Pedal Set that can replace the keyboard's Space / Return / Delete buttons.   To achieve that, we want to use an ultrasonic distance sensor to have the parameter. In our plan, when the pedal touches on the bottom, in the P5, it will type in the key that we planed.   First, we tried the ultrasonic distance sensor on Adriano. To read the distance, it needs the trigger and Echo,  and the distance will be calculated in CM. But I find out when it goes totally close, the number will be around 790.  So we tried to read the number on P.5. And give an if statement to control the action. Also, In the end, it will behave more than one sensor to handle different feedbacks, so it probably will use an array. In the current stage, we only try to have the number in P5, but we do have some problems with that; I think I can have the numbers under the console, but can not use it, probably I don't know how to get rid of " "   We are inspired by t
