This button could be used in all buses. All you have to do is press it when you feel unsafe or in danger and it will immediatly notify the driver. Through an LCD screen and it would say which seat pushed the button so the bus driver could check on the person and remove them from a dangerous situation.

  • Final Week

    Trevor Anderson • 05/05/2025 at 17:48 • 0 comments

    We revised and fixed some problems in the project and we made sure the project is ready to turn in and send out to the world.

  • Real Bus

    Trevor Anderson • 05/02/2025 at 17:09 • 0 comments

    We took pictures of places we could put the button on a real bus for planning. This helped us understand more on how we are going to execute this plan.

  • Week 4 (Hall Effect Sensor)

    Trevor Anderson • 04/21/2025 at 17:14 • 0 comments

    We wired and coded the hall effect Sensor to notify a screen when a button is pressed. The button will notify the driver of the bus saying "Seat _ needs help" depending on what button at which seat is pressed.

  • Week 3 (Coding)

    Trevor Anderson • 04/14/2025 at 17:49 • 0 comments

    We are now working on the coding in Arduino. We have been able to complete the coding for the prototype using Arduino and the buttons on the LCD screen

  • Week 2 (LCD Board with wires)

    Trevor Anderson • 04/14/2025 at 17:39 • 0 comments

    We finished researching and started wiring up and building our model. So now we are just talking about wired. We got stuck on how to wire the parts togeher for a couple days but then we figured it out and finshed wiring the parts together.

  • Week 1 (LCD Board no wires)

    Trevor Anderson • 04/14/2025 at 17:34 • 0 comments

    We did research and put our minds/ideas together to figure out how we going to make the Emergency button a reality to help those who need it most. Then we reasearched what parts we were gonna need, how to wire the parts, and how to code it all.
