Hi!! In my school, me and my friends made a project, an Alarm Clock! And now, you can have one made by YOU! All you need to do is follow this step-by-step tutorial! Make it happen!
Obs: The website “Mundo projetado” was a base for our project, check it out!

### Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

## Step 1:

First, you’ll need to know the materials needed:
-1 computer;

-5 buttons;

-1 buzzer;

- 1 potentiometer;

-1 display;

-22 male-male jumper wires;

-1 Arduino;

-1 USB cable;

-7 resistors - their values must be 100, 300, 500, 700, 900, 1.1k, 1.3k or close.

## Step 2:

1 Step- Here we go! For our first step you’ll need your arduino, your potentiometer, the display, 15 male-male jumper wires and 1 resistor.
Make sure that your first step of the project is exactly like the picture.

## Step 3:

2 Step- you’ll need your 5 buttons, 5 male-male jumper wires, and the rest of resistors.
Make sure that your second step of the project is exactly like the picture.

## Step 4:

3 Step- you’ll need your buzzer, your arduino and 2 male-male jumper wires remaining.
Make sure that your third step of the project is exactly like the picture.

## Step 5:

4 Step- Now the code! You need to download the Arduino App (https://www.arduino.cc/en/Main/Software) and TimeLib(https://playground.arduino.cc/Code/Time). Almost ready! You need to copy and paste the code below in a new document in Arduino App. You just need to upload the code now!
Before you upload, check if the wires are in the right place and the arduino is connected with the computer.
