Week 4

 In the group project, we are trying to make an interactive teddy bear that can make different sounds by touching other parts
of it. 




In the circuit part, we have two different sensors, one is the touch sensor, and the other is a flex sensor. Each one of the sensors is the bear's hands. The touch of different hands can make a different sound. When you touch both hands together, we can have a whole melody. 


To make the circuit, we used a wire wrapper to make the sensor have a longer wire to achieve the bear's hands. And for it can be easily fitted with the bear, we used a smaller size breadboard. But later on, we may also be going to soldering it on the board.




The first question we met is that the speaker's sound is too quiet, so to make it louder, we changed an Arduino Uno, which has a 5.5v output, and that dose helped a lot. 

Coding-wise, we are trying to finger out to separate these two sensors. We used the if statement and also set up the frequency separately. To make those two sensors have a different sound, I changed the number in the frequency map. One is deep sound and the other one with higher sound. 


For the melody one, we referenced the lad we made and changed the note and note duration. And with the If statement, we call the melody only when these two sensors all have input. We are still thinking hard: the flex sensor is too sensitive, and we kindly don't understand how the sensor is influenced by the flex. Because it will make a sound when we reset the sensor position.

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
