This is the #TBT or Tooth Brush Timer. Did you know that the recommended time by dentist to brush your teeth is two minuets. The #TBT eliminates the hassle of having to try keeping track of time yourself or having to set a timer on your phone each time you brush your teeth.

The way the #TBT works is that after the user flips the switch it starts a prep timer of 20 seconds accompanied by leds that allows for users to get their tooth paste and tooth brush ready. After the prep timer is up all the leds will be green. Once the actual timer starts each led will tick purple every 11 seconds until they are all purple. After the first 110 seconds and all the leds are purple (there are 10 leds) they will tick one by one to blue for the last 10 seconds. After these last 10 seconds are up all the leds will collectively blink red to alert the user that they are finished and to flip the switch back.

In making this prototype two adafruit tutorials from adafruit learning were used. One where users are taught to use a switch to turn leds on and off and another where users are taught to make a timer for washing hands.
