I worked on this project by myself. My idea was to make a sensor that could notice that the lights are on and alert me by showing an image on the micro bit or play a song to tell me they are still on. The main reason I chose to use this idea was because of the number of times that I forgot to turn off lights in my house which could lead to them burning out. So I thought that making a sensor that notices a light is on too long would be a great solution. How I thought I could create this would be using code to make a light sensor by making the led lights on the micro bit test how much light is falling on the display.
