Charging Reminder

Introduction

Are you bothered by forgetting things? I am seriously bothered by it. Charging the computer is my daily routine because I will use it every day in school. However, I often forget to charge it which I'll have an out battery computer the next day. To avoid this problem, I make a project to remind me of charging my computer.

Materials

< Arduino Components >

1. Arduino Leonardo board x1 - Actually every kind of Arduino board is fine.

2. LED lights x3 - Lights for turning on. (No limit of LED lights' colors)

3. Yellow resistance x3 - Components for LED lights.

4. Photosensitive resistance x1 - The sensor that senses the

5. Blue resistance x1 - Components for photosensitive resistance.

6. Arduino wire x20 - Connecting every component to the Arduino board.

< Outward appearance >

1. Box x1 - Placing the Arduino board.

2. Paint Brush x2 - Paint the outward appearance of the project.

3. Black color paint x1 - The color of the project's outward appearance.

4. Utility knife x1 - Cutting holes for components that need to be outside of the box.

LED lights and the Photosensitive resistance are the two parts of this circuit diagram. (Just for remind, the resistance that I circled need to be the blue one.)

Plug your components by the circuit diagram above. Remember to connect your Arduino board and the computer together so you can test the "Serail port monitoring window" which makes sure whether the photosensitive works.

I use the Arduino block to build up my code.

Link

1. Download the code of this project from this link: https://create.arduino.cc/editor/alicia0616/fcc606...

2. Unzip the archive.

3. Upload this code to your Arduino program as your project.

Serial port (Need to change)

In this project, the photosensitive resistance sensor by the value of brightness. However, the correct numerical value depends on the light value of the condition you are staying at. Therefore, you can check your own numerical value in the "Serail port monitoring window".

Components

1. Poke holes for the three LED lights and the photosensitive resistance.

2. Install three LED lights on the upper left corner of the box.

3.. Install the photosensitive resistance in the middle of the box.

Decorate

1. Hide the Arduino board and wires inside the box.

2. Cut the hole for the computer cable that starts this project.

3. Color the whole box in colors that you like. For me, I color the box into black.

To stop the light from the LED lights, just plug in the charger before you sleep. In the next day, you will have a full charge computer!
