Paper Sequencer Project by Adan Suleiman, Yazan Daoud and Nashwa Jaber:

Paper Sequencer is an auditory device designed to emit a distinctive sound upon detecting a black square within any of its five discs.

Our user can:

• Upload new sound files via a webpage or simply enjoy our pre-downloaded default sounds!

• Start and stop the system: click to start and click to stop the disks from spinning!

• Control the volume: move a button left and right to raise and reduce the volume!

Folder description :

You can find the following files:

• Servo_with_click_arduino.ino: An Arduino code that runs servo in a constant speed and a button can be attached.
• Audio_and_sensor_simple_test.ino: A test that takes an audio file from an SD and releases it once the sensor encounters a black square.
• Audio_with_SD_simple_test.ino: A test that takes an audio file from an SD and starts playing it.
• final_code.ino: Our project's main code.
• user_interface.html: Our user interface webpage.
• http_handling.ino: using esp32 as an access point.
