Drink Reminder
Overview
Its a well known fact that people of all ages should regularly drink water. This keeps hydration levels up and improves concentration in the workplace and classroom.
In this lesson students will design and code a drinks reminder. They will learn how to program an external vibration motor to work in conjunction with the micro:bit LED matrix.
Aims
- Learn how a vibration motor works.
- Create a system that helps people for everyday life in the workplace and classroom.

Kit Required
Micro:bit
Innovation Board
Vibration Motor
- Connector Cable
Preparation
- Connect the micro:bit to the Innovation board via the edge connector.
- Use the connector cables to connect the vibration motor to the ADC1 connector on the Innovation board.
- Connect the micro:bit to a computer via the microUSB cable.
- Go to the MakeCode website on your computer and open a new project.
Time to Code
What Will Happen
When the micro:bit is powered the vibration motor will vibrate for 1 second and then stop for 1 second. At the same time as the vibration the LED matrix will light up for the same period of time and will turn when the vibration motor turns off. This will repeat 4 times.
After the 4 repetitions the micro:bit will begin a countdown of 30 minutes. After 30 minutes the code will restart and the vibration motor and LED matrix will again vibrate and light up 4 times.
This code is in a forever loop so will continue whilst the micro:bit is powered.
Taking it Further
- Add other components to the drink reminder system.
- Create a timer setting so the time in between each reminder can be varied.
