This app uses voice recognition to execute voice commands to control the headlight. For example, the user can turn on, off the headlights, or they can change their color by saying corresponding keywords. This app uses bluetooth to connect to the headlight device, which consists of a microcontroller attached to a LED board. These hardware parts are protected by a 3D-printed case, and the whole device is attached to a wearable elastic band.

When doctors perform operations, often they use headlights. However, having to turn on and off headlights themselves is an inconvenient task during operations. To address this issue, this project assists medical staff by using voice recognition to control the headlights.
