This week is kind of hard for me since I do not have any coding backgound.
I planned to build an app interface with AppInventor since I do not have any coding background.
This is the code that I wrote.
I need to install Emulator since I do not have an android phone.
This is the "app" that I built. However, it is not recording anything. Therefore, I decided to use try python instead.
I decided to write something that is able to record the sound. I followed the instructions here.
First, I tried with this code to record a few seconds of audio and save to a WAVE file.
It worked! Then, I used this code to playback the recorded audio.
Do not forget to installed the sounddevice library.
However, I have trouble to getting my board to talk to my computer. I decided to use Neil's code from last week. I modified the code and tried to make it to generate the signal received by the microphone.
This is the text of sound signal that my input devices generated.
