In the first week of school, we started the operation of the second-year project 'Sensor-Based Contactless Musical Instrument', which means that users can obtain sound only through induction without directly touching the strings. The functionality of this 'guitar' will be continuously expanded during the project’s implementation. In the first week, we will complete the following five main tasks: 1. Understand the basic principles of guitar. 2. Test the Arduino Uno. 3. Completed the testing of six IR sensors and ultrasonic sensor. 4. Completed the buzzer and speaker tests. 5. Match the six IR sensors to the different frequencies of the speakers. First, we test the Arduino Uno through the computer to understand its functions and programming methods. Connect the six IR sensors to the computer respectively, and judge whether there is an object approaching the IR sensor based on the returned grayscale or distance value. After completing the six IR sensor tests, the ultrasoni...

This week is the last week of the entire project, and the main functions of our project will be completed this week. All tasks include the following: 1. Complete the guitar part code. 2. Use switches to control transitions between instruments. 3. Use ultrasonic sensors to control changes in pitch. 4. Complete the poster production. First, we complete the adjustment of the ultrasonic sensor. By changing the distance, the changes in the piano's tone can be controlled. Secondly, the code for the guitar instrument is also completed this week. Changes in chords can also be controlled by changing the distance of the ultrasonic sensor. Then we adjusted the circuit again. Add switches to control switching between instruments. Final version of code Python part Mainly used serial and pygame libraries. The core approach of the code snippet is to receive the signal  sent by Arduino through serial communication and play the corresponding audio file based on the content of the signal. Audio file...
