For the final demo, we added the other keys and integrated the bluetooth component into the circuit. Once we had one key working, we can replicate the circuit to do the same for the other 5 keys. The frequencies were transmitted over bluetooth to a speaker, where the note was played.įor the first demo day, we built one of the keys and hooked it up to the speakers so that when covered it would play a note. Each light sensor/key was associated with a button so that when the button was pressed, the light sensor values were read in.
The analog values of the light sensors were used to create the range of frequencies from the key to the key’s sharp. Potentially include LEDs to blink along with the music we create if timeīoth of us are interested in music, so we built a hybrid keyboard/DJ board that utilized light sensors as keys.
Plan to have the Arduino read the analog sensor values even if these do not include sound.īy April 17th, we will have finished the entire project. Will then use matlab to translate these raw figures and produce an audio track based on theīy April 3rd, we will have finished the mechanical design and general hardware design, as wellĪs acquire all electrical components necessary to complete the project. The analog output of the sensors will be captured in real-time through a wireless network. There will also be buttons and other arrangements of light sensors that create different sounds. Will use sliders to (partially or wholly) cover the light sensors in order to signal a distorted noise. Three light sensors arranged together will function as keys. This project is a musical keyboard/DJ board that utilizes Arduino Uno (with wifi) andĪrrangements of light sensors.
