Step 1: Components List

The acrylic plates are fragile, so please be careful when assembling them in case of breaking.

The acrylic plate is covered with a layer of protective film. You need to remove it first.

Some holes in the acrylic may have residues, so you need to clean them before the use.

Step 2: About the Adeept Digital Clock

Overview

Digital clock is a timing device that shows seconds, minutes, and hours on an LED display with digital circuit. Compared with traditional clock, it is more accurate and shows the time directly without mechanical drive, thus it's widely used. The Adeept Digital Clock is a multifunctional digital clock module that includes Arduino Nano board, buzzer, 7-segment LED displays, and clock chip.

Features

This digital clock shows the time and the temperature of the RTC chip and sets the time and alarm via two keys. The brightness of the LEDs is adjusted automatically by detecting the changes of ambient illuminance.

Connect the digital clock module to power and it will show "AdEEpt" in a rolling way and then the current time. Press Key 2 and the screen will change from the time to the temperature of the RTC chip. Due to program setting, Key 1 now doesn't work. Press Key 2 again and the display will again show the current time. On this screen, press Key 1 for the first time, the LED display will show letters "tE" and then you will enter the time setting mode. The first 7-segment LED will start flashing. Press Key 2 and you can then set the tens digit of hour; press Key 1 again, the second LED flashes, and you can set the unit digit of hour; press Key 1 for the third time, the third LED display blinks, and you may press Key 2 to set the tens digit of minute; press Key 1 again, the forth LED display will flash and you may set the unit digit of minute; press Key 1 for the fifth time, the whole display will show letters "AC" and then enter the alarm setting mode. Under this mode, the first 7-segment LED display begins to flash. Now you may press Key 2 to set the tens digit of hour; press Key 1 for the sixth time, the second LED flashes, and you can set the unit digit of hour; press Key 1 for the seventh time, the third LED display blinks, and you may press Key 2 to set the tens digit of minute; press Key 1 again, the forth LED display will flash and you may set the unit digit of minute. Press Key 1 for the ninth time, the screen will return to show the time when saving the time and alarm just set. When the time is up, the buzzer will beep to alert; press Key 2 and it'll stop beeping.

Step 3: What Is Arduino?

Arduino is an open-source electronics

platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing.

Over the years Arduino has been the brain of thousands of projects, from everyday objects to complex scientific instruments. A worldwide community of makers - students, hobbyists, artists, programmers, and professionals - has gathered around this open-source platform, their contributions have added up to an incredible amount of accessible knowledge that can be of great help to novices and experts alike.

Arduino was born at the Ivrea Interaction Design Institute as an easy tool for fast prototyping, aimed at students without a background in electronics and programming. As soon as it reached a wider community, the Arduino board started changing to adapt to new needs and challenges, differentiating its offer from simple 8-bit boards to products for IoT applications, wearable, 3D printing, and embedded environments. All Arduino boards are completely open-source, empowering users to build them independently and eventually adapt them to their particular needs. The software, too, is open-source, and it is growing through the contributions of users worldwide.

Step 4: Why Arduino?

Thanks to its simple and accessible user experience, Arduino has been used in thousands of different projects and applications. The Arduino software is easy-to-use for beginners, yet flexible enough for advanced users. It runs on Mac, Windows, and Linux. Teachers and students use it to build low cost scientific instruments, to prove chemistry and physics principles, or to get started with programming and robotics. Designers and architects build interactive prototypes, musicians and artists use it for installations and to experiment with new musical instruments. Makers, of course, use it to build many of the projects exhibited at the Maker Faire, for example. Arduino is a key tool to learn new things. Anyone - children, hobbyists, artists, programmers - can start tinkering just following the step by step instructions of a kit, or sharing ideas online with other members of the Arduino community.

Step 5: How Should I Use Arduino?

If you are a beginner with Arduino, Arduino learning kits on our website www.adeept.com would be a prefect step into this fantastic field!

An Arduino board used in the clock kit: Arduino NANO V3.

Power

The Arduino Nano can be powered via the Mini-B USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source.

Memory

The ATmega328P has 32 KB, (also with 2 KB used for the bootloader. The ATmega328P has 2 KB of SRAM and 1 KB of EEPROM.

Input and Output

Each of the 14 digital pins on the Nano can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. In addition, some pins have specialized functions:

● Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data. These pins are connected to the corresponding pins of the FTDI USB-to-TTL Serial chip.

● External Interrupts: 2 and 3. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. See the attachInterrupt() function for details.

● PWM: 3, 5, 6, 9, 10, and 11. Provide 8-bit PWM output with the analogWrite() function.

● SPI: 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK). These pins support SPI communication, which, although provided by the underlying hardware, is not currently included in the Arduino language.

● LED: 13. There is a built-in LED connected to digital pin 13. When the pin is HIGH value, the LED is on, when the pin is LOW, it's off.

The Nano has 8 analog inputs, each of
which provide 10 bits of resolution (i.e. 1024 different values). By default they measure from ground to 5 volts, though is it possible to change the upper end of their range using the analogReference() function. Analog pins 6 and 7 cannot be used as digital pins. Additionally, some pins have specialized functionality:

● I2C: 4 (SDA) and 5 (SCL). Support I2C (TWI) communication using the Wire library (documentation on the Wiring website).

There are a couple of other pins on the board:

● AREF. Reference voltage for the analog inputs. Used with analogReference().

● Reset. Bring this line LOW to reset the microcontroller. Typically used to add a reset button to shields which block the one on the board.

Step 6: Arduino Software (IDE)

Arduino Software (IDE) is used to write and upload the code for Arduino Board. First, install Arduino software (IDE): visit https://www.arduino.cc/en/Main/Software. Download the corresponding installation program according to your operating system. If you are a Windows user, please select the “Windows Installer” to download and install the driver correctly.

After the download completes, run the installer. For Windows users, there may pop up an installation dialog box of the driver during the installation. Please agree the installation when it appears.

After installation is completed, an Arduino software shortcut will be generated on the desktop. Run the IDE.

The Arduino Integrated Development Environment - or Arduino Software (IDE) - contains a text editor for writing code, a message area, a text console, a toolbar with buttons for common functions and a series of menus. It connects to the Arduino and nano hardware to upload programs and communicate with them.

Verify: Checks your code for errors when compiling it.

Upload: Compiles your code and uploads it to the configured board.

Before uploading your sketch, you need to select the correct items from the Tools > Board and Tools > Port menus. The boards are described below. On the Mac OS X, the serial port is probably something like /dev/tty.usbmodem241 ( nano ) or /dev/tty.usbserial-1B1 (for a Duemilanove or earlier USB board), or /dev/tty.USA19QW1b1P1.1

(for a serial board connected with a Keyspan USB-to-Serial adapter). On Windows, it's probably COM1 or COM2 (for a serial board) or COM4, COM5, COM7, or higher (for a USB board) - to find out, you look for USB serial device in the ports section of the Windows Device Manager. On Linux, it should be /dev/ttyACMx, /dev/ttyUSBx or similar.

Once you've selected the correct serial port and board, press the upload button in the toolbar or select the Upload item from the Sketch menu. Current Arduino boards will reset automatically and begin the upload. With older boards (pre-Diecimila) that lack auto-reset, you'll need to press the reset button on the board just before starting the upload. On most boards, you'll see the RX and TX LEDs blink as the sketch is uploaded. The Arduino Software (IDE) will display a message when the upload is completed, or show an error.

When you upload a sketch, you're using the Arduino bootloader, a small program that has been loaded on to the microcontroller on your board. It allows you to upload code without using any additional hardware. The bootloader is active for a few seconds when the board resets; then it starts whichever sketch was most recently uploaded to the microcontroller. The bootloader will blink the on-board (pin 13) LED when it starts (i.e. when the board resets).

Note: If you are using an external programmer with your board, you can hold down the "shift" key on your computer when using this icon. The text will change to "Upload using Programmer".

New: Creates a new sketch.

Open: Presents a menu of all the sketches in your sketchbook. Clicking one will open it within the current window overwriting its content.

Note: Due to a bug in Java, this menu doesn't scroll; if you need to open a sketch late in the list, use the File | Sketchbook menu instead.

Save: Saves your sketch.

Serial Monitor: Opens the serial monitor.

Additional commands are found within the five menus: File, Edit, Sketch, Tools, and Help. The menus are context sensitive, which means only those items relevant to the work currently being carried out are available.

Since version 1.0, files are saved with an .ino file extension. Previous versions use the .pde extension. You may still open .pde named files in version 1.0 and later, and the software will automatically rename the extension to .ino.

Step 7: Install Library

The examples provided in this article use three library files.Are respectively., so you need to install it before compiling.

Step 8: Upload Program

After the preparations above, next we will upload the program (example sketches provided) to the nano board.

Open the program provided for the control board, the file “clock.ino”.

Connect the Arduino nano board to the PC. Select Tool -> Board “Arduino nano”, and Port - > COM16. Also here is COM16, assigned to the nano, but it can be COM1, COM2, COM3...

Step 9: Assembly
