Student support is a board-bracelet combination to be used by a student and teacher, respectively. Using bluetooth connectivity between two Bluefruit microcontrollers, the student can send a signal via the board to the teachers wristband, which will cause it to start vibrating, informing the teacher that someone has a question.

Have you ever been at the back of a big lecture hall, maybe a little shy to ask a question? Have you ever had a professor that can't seem to notice you have something to say? Student support eliminates these issues by allowing an instant way of "raising your hand." Any student can send a signal to the teacher for whatever reason to get their attention. 

• Students who find it difficult to ask questions during lecture

• Teachers who want to improve the classroom learning experience for their students

We have two Adafruit circuit playground microcontroller that communicate with each other using bluetooth. A signal is sent from the one that that the student is using when the conductive fabric is pressed. The numeric value is depended on the position of the potentiometer. The Bluefruit microcontroller on the teacher's wristband takes the sent value and then sends it to the vibration motor alerting the teacher to the students question. The code for this project can be found here

Given more time, we would:

• Make the design more professional / less wires sticking out

• Improve the distance of communication between devices

• More functionality (specifics to ask a question, explain something further, etc.)

• Possibly more stimulus for teacher's wristband for other ways to grab attention

• Have a network of students using them at once to have a "net total" vibration sent to the teacher
