Arduino Project- to Remember You to Bring Your Thing

By: Weber Wu

This year, I am having a Arduino class, I told my teacher that I want to make a device that Let me to Bring My things. I want to make this device is because I like to play golf, but I sometimes forgot to bring the card. ( The card is to buy the practice golf balls, I sometimes forget to bring it. )

So, this time I want to make this Arduino Device.

These are the supplies I use to make this Arduino Device:

1. A Arduino Leonardo Board

2. Servo motor

3. 12 cm electric wire

4. 30 cm electric wire

5. solderless breadboard

6. Ultrasonic sensor

7. A Shoebox

This is step 2 on my Arduino project.

The materials that we need to use in step 2:

- shoebox

- Arduino Leonardo Board

- Breadboard

In this step, we need to put the Arduino Leonardo Board and the Breadboard in the shoebox, and poke 2 holes and the left and right in the shoebox, so we can put the wires in the holes and out.

This is step 1 of my Arduino Project.

In Step 1, the materials that we need to use is:

- Servo motor

- Ultrasonic sensor

- 2 12 cm electric wire

- 30 cm electric wire

- Arduino Leonardo board

- Solderless Breadboard

In the First Step, we need to put the 30 cm electric wire to the Servo motor and the Ultrasonic sensor.

And put the 12 cm electric wire from the Arduino Leonardo board to the solderless breadboard.

Last, put the 30 cm electric wire to the Arduino Board and the Solderless breadboard.

Materials for step 3:

- Cardboard ( to make the lock )

- servo motor

- Ultrasonic Sensor

step 3, I make the shoe cabinet a lock so I can control it lock or unlock. And I make a hole in the shoebox and put the golf card in the hole, and use the Ultrasonic sensor to sensor if the Ultrasonic sensor is shorter to (<) 10 cm, then the lock will be locked but if the sensor is longer or same as (>=) 10 cm, it will be unlocked. and when we finished that, we can test it and let it work!

Materials I use in this step:

- Arduino

- Ardublock

I use Ardublock to make this Project, Ardublock is in Chinese, so sorry for the inconvenience. Thank you.
