This is a screenshot of coding in progress! This is the time where we figure out how to perfect the coding of this micro bit to make a timer to remind us when to drink water.

How are we coding this?

First, we need to figure out how to make the timer go off about every hour so that the LED turns on at the proper time. Next, we are going to have a certain button that is pressed after the timer goes off and the LED turns on so that it can reset quickly for another hour without much hassle. The timer is going to count down by minutes as to not be annoying when it counts every second for an hour.

Stick around to find out how we improve our micro bit design and coding!

Engineering Design Process

Have you ever gone through the day, unaware of your water intake? Do you get the thought in your head that you did not drink any water or not enough? Well, here is a new innovation for you!

My partner and I decided it would be a great idea if we created something that would benefit people’s health. We started thinking about something that affects numerous people that they might even be unconscious about. Then, the idea came to us. Most people, including us,  do not drink enough water. We focus more on our eating or exercising maybe, but we underestimate the importance of water. Now, how do we solve this problem? By coding a micro bit, we can program a portable light to turn on at certain times of the day to remind us that we need to drink water. But there is a problem… How do you know the light is turning on if you cannot see it? Putting it in a pocket or in a backpack or bag is not going to be effective. How can we find a solution? We can make it convenient by turning it into a bracelet! Micro bits are compact and can easily fit on most wrists. With a stretchy string, we can make a simple, yet useful bracelet to help remind us when we need to drink water!
