ECE 5725 Final Project

For the final project, we wanted to build a gesture controlled instrument. In this project, we utilized several sensors to receive the input gestures. When the input detected, the corresponding sound will be displayed, and the corresponding key name will show on the screen with its own color.

At first, we used the HC-SR501 Pyroelectric Infrared PIR Motion Sensor to detect the input. However, as the block time of this sensor is 2.5 second, two inputs for the same key can only be detected once. Also, the block time is hard to adjust. So, we changed our sensors to be IR Break Beam Sensor.

For the final version, there are 7 sensors to receive the gesture inputs from the user, each sensor sends the input to its GPIO pin. The corresponding sound and key name will be displayed according to the input.
