Voice Recognition System

  Week 4 Feb 25 th In this lab, we added more functions to code. We also add sound sensor as well as configured it to adjust to certain noise in the room. At first, we tried the code we wrote before and successfully done all the command. However, after we added the new code, the LEDs began to flash randomly. We thought it might be the problem of delay, so we modified our code and called the command again. Then we found another problem that all lights going on when the commanded hadn ’ t be called. To solve this problem, we modified the code again and tried for times. We had a brief meeting about expectations concerning bench inspection after we solved the problem. We found the screen cannot show all the words clearly, so we adjusted the sensitivity and try to record the response and command. However, that ’ s not so successful and we had to leave the room because of the time limit. We discussed and decided to take this project after class. Next week will be bench inspection, so our...

  Week 3 Feb 17 th Our o rdered part arrived and we retrieved it from the lab technician. After attended to lab, we h ad a small brief about the expectations with the poster, blog, and the ethics report.   Then we b egan finding pin connections for the grove sensor. At first, we i ntegrated grove speech recognizer to breadboard with Arduino.   T he grove speech recognizer Arduino successfully powers on after connecting USB.   Secondly, we i ntegrated LED with grove speech recognizer and Arduino.   After that, we m odified the code to turn on the LED with the grove speech recognizer.   The LED turns on with the given functions in the documentation . We can call HICELL command   to  turn on the LED.   We a ttempted to add new voice functions by training grove speech recognizer , however, we realized we can no t   achieve the desired affect after all . We d ecided to use the pre   given functions to complete t as ks as ordering a ...

  Week 2 Feb 10 th We r etried to make Arduino function   after the lab start . After further research, browsing through multiple forums, suggestions around the error code include, we found that the Arduino ports being a main issue. When we s witched the Arduino to a personal computer and the Arduino ports show up, meaning library pc does not register Arduino. However, when we u sing personal laptop with a proper port ,  the Arduino persists to refuse to upload the code. So we s earch ed  further forums and online resources such as Arduino nano documentation, then we found the Arduino IDE is a potential issue as well. To prevent it, we s witch ed  the IDE from 1.8.19 to 1.8.3 an older model the code uploads the program without any error. We redid the simple blinking light program, the LED flashes in the given sequence.   We i ntegrated the sound sensor with aid of a diagram. The sound sensor records the intensity of sound in the room and is displayed in the...

  Week1 Feb 3 rd We found our lab time was in a clash and asked teacher for the solution. The result is we were decided to had our lab on Friday afternoon because all of us are free. In the first group lab, we picked up ordered parts from the lab technician . T he ordered parts included : ·  Arduino nano ·  USB-Type A to Type A plug ·  150mm (about 5.91 in) Male to Female jumper wires ·  Breadboard ·  LED’s ·  Two microphone sensor Modules ·  Jumper cables ·  Arduino display ·  Through hole resistors The only parts that were picked were the Arduino nano, its display, the USB connector, and the sound sensors. The rest of the parts were available from the lab. The methodology of the first lab is ensure every part we ordered worked as intended. However, we found two problems stopped our lab: ·  USB Type A to Type A too large ·  Arduino not turning on The solution of the first problem is r equest a smaller USB from the lab.   ...
