Ideas for Arduino School Project

Hello, for a school project I am required to implement Arduino and the devices I have been given to address a community-related issue. This issue has to pertain to a target audience (e.g visually-impaired, elderly, etc) and an issue that they face.

The devices that are provided:

  1. 1 Ultrasonic Sensor

  2. LDRs

  3. Pushbuttons

  4. LEDs

  5. 1 Servo Motor

  6. 1 Buzzer

I am strictly limited to these devices so the project idea must be possible with only these items + Arduino.

I need some help thinking of project ideas as everyone in the class has to have a unique idea and this is my first time working with Arduino. Any suggestions or help would be appreciated.
