How to Create a Clock with Arduino from Scratch

Making, creating or building a clock with Arduino software is extremely easy as well as useful if at any time you have needed to know the time within an application, program or tool, since with an Arduino clock you can do it.

For starters, in case you’re wondering what is an Arduino? This is a software or platform to create open source, Arduino is based on free software and hardware systems.

If you do not know what free software or free hardware is, these refer to freedoms that users will have with respect to them. Free software or hardware can be modified in any way.

Because the Arduino works with a free software or hardware system, anyone can create applications, programs, tools or clocks. In case you are interested in knowing how to create a clock with Arduino, we recommend that you continue reading.

What are the chances of having an Arduino board?

By having an Arduino board the possibilities are wide, because this is a board that has a series of microcontrollers that allow a great possibility for the creation of various devices, such as a home automation house (it is a house that has a remote control system, where you could manipulate from electricity, the opening of the doors among many more options), you could play chess from a distance, create music, create doodle robots (which are robots that can draw certain types of figures default) , however, this time, we will focus on watches with this type of technology.

Creating a clock with this software is something basic and simple to achieve a customizable digital clock, due to the wide variety of control possibilities that the Arduino board has.

How does an Arduino work?

The Arduino board is a board that contains ATMEL-type microcontrollers, which are integrated controllers, in which specific instructions can easily be recorded, these instructions interact with the controllers in order to create programs that interact with the entire circuit.

Seen in this way, it could be interpreted that it is a difficult task, but once we have knowledge of the input interface (which is a connection that allows us to interact with other peripherals) the information that arises after this connection goes directly to the controller, which will be in charge of internalizing the supplied data ; as well as it has an output interface which allows sharing the information found inside the Arduino controllers to other peripherals connected to this interface.

What materials do I need to create the Arduino clock from scratch?

Thanks to Arduino technology it is possible to make, create or build a digital clock in a simple way and configure it in a personalized way. Thanks to the Arduino digital inputs and outputs it is possible to create or design multiple codes for programs , applications or tools, such as clocks.

What you need to create your clock with Arduino is; an Arduino UNO, a display that has 4 digits and 7 segments, a board to install the circuit, a battery to power the clock with Arduino , 6 recommended 220 ohm resistors and finally a set of cables.

In the same way, it will be necessary to install a library for this type of system , the best option is to install a free Time.h. You can install it through a library manager or “Add .ZIP library”.

Once you have all the materials you can design a digital clock thanks to the Arduino boards. In addition, with Arduino boards it is possible to turn on and program LED strips very easily.

Steps to make, create or build a clock with Arduino

Once you have all the materials to create or build a clock with Arduino it is necessary that you identify the pins for your clock with Arduino. In the 7-segment display that you chose, you must set 4 pins to indicate which digit will light up, while the others will represent the segments of the digits for the Arduino clock.

Once you identify the pins for your clock, the first step is to assemble the circuit, for it, you must connect the Arduino UNO board with the 7-digit display , for this you will use the set of cables you have chosen.

Additionally you can add a button or push button , it is advisable to add two buttons to the circuit, since with one you can change the time, while with the second you can set the minutes.

After you elaborate your circuit with the physical components for your clock with Arduino you must download a code for the digital clock with Arduino, these codes can be found in a Time.h library.

Steps to load the program with Arduino

Once you have assembled your circuit, you can load the program or code for the digital clock with Arduino, for this it is necessary that you use your PC , with this you can install the code and thus create, build or make your clock with Arduino .

When loading the digital clock program with Arduino it is necessary that you disconnect the pin of your circuit with which you send the information through the serial port.

After you finish loading the program or code for digital clock with Arduino you can connect the pin again. Then you can press the “Reset” or “Start” button for the program to start working.

If the program has been installed correctly, you will be able to set the time of your digital clock with Arduino with the buttons that you previously installed. Additionally you can install a battery in your new digital clock with Arduino to power its circuit.

What price can make a clock with Arduino?

The price usually varies according to the functions, applications, or characteristics that it could have, it could cost from $ 5 which would come with functions and simple design, but the amount could change depending on the producer, the place of manufacture, the transfer , among many other factors that tend to directly influence the cost of an item.
