Arduino_Music_Piano_Synthesizer

Project for IEEE hackathon

Description

This piano systhesizer is controlled by 8 buttons with 256 combos but only output with one cable.

• All combos can be programmable with music nodes.
• Used r2r ladder DAC in order to minimize inputs used (only 1 input), make programming easier and make it possible to detect key pressed without any delay. (No need for shift register nor 8 individual Digital Input but one analog input).

In addition, 2 potentiometers are used for controlling upper and lower frequency bounds. Meanwhile, 2 black buttons(software enabled latch system) function as record and play button. The wireless control module on right side is used for controlling pitch, delay, and MUTE during playing.

Hardwares Used:

• 1. nRF24L01+ 2.4GHz wireless module x 2
• 2. Gyro. + Acc. module
• 3. 2 x Arduino UNO
• 4. 1k resistors and other resistors
• 5. LEDs
• 6. push buttons
• 7. wires
• 8. speaker
• 9. battery packs x 2
