There\u2019s still a lot of prejudice in \u201cbig business\u201d against Arduino solutions. One point of criticism is surely that Arduino hardware software come from an open source platform. This fact makes the system \u201cimperfect\u201d, occasionally \u201cunsafe\u201d and more difficult to design at first sight. However, do you dare taking a second glance? In the following article, you\u2019ll learn about the advantages and chances which might balance Arduino\u2019s weak points in B2B environments.<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

First of all, the Arduino system offers a great environment for innovation at a low-cost basis. So it does not surprise anyone that Arduino perfectly covers the need of tech start-ups around the world. By the way, \u201clow cost\u201d does not equal \u201clow budget\u201d, as this term is often used with the dismissive connotation of outcomes with lower quality standards. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The Arduino ecosystem includes both hardware and software aspects which perfectly work together. It was designed as an open platform for everyone with individual hardware and software projects and even includes its own programming language (C or C++ based) for an easier handling. All hardware components and circuit boards can be used within many IoT settings. For example, we and our partner companies rely on Arduino technology for our USB pushbuttons, USB pushboxes<\/a> and all solutions concerning robotic lawn mowers<\/a>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

There are many components that you can equip your Arduino board with, for sure.\u00a0 Basically, every board includes the following components.<\/p>

  1. Microcontroller<\/strong> -the \u201cbrain and memory\u201d of an Arduino which we load programs into. It works like a tiny computer with a limited amount of operations.<\/li>

  3. USB to Serial chip<\/strong> – helps translating data transmitted from another device to the on-board microcontroller.<\/li>
  4. Digital pins<\/strong> – use digital logic (0,1 or LOW\/HIGH). You commonly use them for switches and to turn on\/off an LED.<\/li>
  5. Analog pins<\/strong> – read analog values in a 10 bit resolution (0-1023).<\/li>
  6. 5V \/ 3.3V pins <\/strong>– power external components.<\/li>
  7. GND<\/strong> – ground, negative or you simply use it to complete a circuit where the electrical level is at 0 volt.<\/li>

    A circuit is always a matter of pins and wires when it comes to Arduino boards. Basically, for a LED circuit, you just need to connect a selected pin to a GND pin. At a LOW state, the LED stops glowing until the current flow moves on to a HIGH state again. Circuits are typically represented as schematics, which are the blueprints for your circuit.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    Analog and digital signals are another important aspect of all electronic circuits. With no exceptions, analog signals are generally bound to a range. In an Arduino, this range is typically 0-5V, or 0-3.3V. With a potentiometer (an analog component used to change the resistance of a circuit), we can manually adjust this range (0-5V). In the Arduino program, this is represented in a range of 0-1023 (10-bit resolution). For example, by writing an analog signal using Pulse-Width Modulation (PWM), you can use a range between 0-255, as we are using an 8-bit resolution.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    In contrary, a digital signal represents only two binary states (0 or 1) that are read as high or low states in the program. This is the most common signal type in modern technology. Thus it is easy to read and write digital signals on an Arduino. Digital signals might seem very basic (just 0 or 1), but are actually way more advanced. For example, you can create a binary sequence (also: bitstream) by sending a high or low state rapidly a number of times.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    Working with Arduino always means sensors and actuators. So it is important to know the difference between these elements. In simple terms,\u00a0 a sensor records a physical parameter and converts it into an electronic signal. For example, when a circuit state changes after you pressed a button, the electronic signal is switched from low to high (0 to 1). In fact, we find this principle in many electronic devices in daily life, like in vacuum cleaners and microwaves. There are digital and analog sensors on each Arduino board.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    An actuator effectively changes a physical state. Some common examples are LEDs, motors and switches. Generally, actuators convert electric signals into e.g. radiant energy (light) or mechanical energy (movement). How actuators are controlled really depends on the component in question. One simple way is to simply turn something on\/off, while more advanced is controlling the amount of voltage a component receives. In a nutshell, a sensor senses and transmits input triggers while actuators transform these triggers into an effective output.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    The Arduino ecosystem includes several types of serial protocols, especially when transmitting data of digital signals. Among all protocol types, UART, SPI & I\u00b2C are most common. Serial communication runs via a so-called serial bus, which is attached to a specific pin. Apart from the protocols, Arduino boards naturally have a memory, which is usually a SRAM or flash memory.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    While an SRAM memory automatically resets after being switched off, a flash memory doesn\u2019t and keeps all saved data. How much memory is available on an Arduino varies from board to board. In order to save programming work, you can also use a board with an embedded sensor.

    For example, the Nano 33 BLE Sense has 7 embedded sensors, but is only 45x18mm (the size of a thumb). All these sensors are connected via the I\u00b2C protocol and have a unique address. Another feature which makes Arduino boards the perfect fit for IoT projects is an embedded radio module. Maybe you already know these modules as Wi-Fi, Bluetooth\u00ae, LoRa\u00ae, GSM, NB-IoT, but there are many other options available depending on your requirements.

In order to program your board, you need to write a program, compile that program into machine code, and finally: send over the new program to your board.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    The Arduino IDE is a program, or application, that you can download (or use an online version), to manage all of your code development. Due to this support, everyone can learn how to get an Arduino project running, even without a lot of previous knowledge. These days, you can switch and select between three versions of Arduino IDE, which are IDE 1.8.x<\/a> (classic), IDE 2.0.x<\/a> (new) and Web Editor<\/a> (online). You should also download libraries with ready-to-go code examples which make programming easier for you. Especially for bigger projects, you can also rely on the IoT Cloud<\/a>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    Preparing an Arduino board and uploading code on it usually follows a step-by-step procedure. This is what the Arduino documentation describes as a \u201ctypical workflow\u201d.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    1. Install your board!<\/strong> This means installing the right Core Specific API for your board. Otherwise you cannot use it. You can install the \u201cpackage\u201d directly within the IDE.<\/li>
    2. Create a new sketch!<\/strong> A sketch is the main program file for your project. Basically, it includes the instructions which the microcontroller is to execute.<\/li>
    3. Compile your sketch!<\/strong> In this step, you check your code for errors, and convert it into a binary file (1s and 0s). If something fails, the error console alarms you. Please consider that the written code is not exactly how it looks like when you uploaded to your Arduino.<\/li>
    4. Upload your sketch!<\/strong> After a successful compilation you can upload the code to your board. In this step, you connect the board to the computer physically, and select the right serial port.<\/li>
    5. Tip: Use the Serial Monitor (optional)!<\/strong> For most Arduino projects, it is important to know what’s happening on their boards. The Serial Monitor tool available in all IDEs allow for data to be sent from your board to your computer.<\/li><\/ol>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

      Are you still wondering if and why Arduino-based projects can be an option for your company? First of all: Not everyone might profit from it and there is never the \u201cone and only\u201d way to success. However, you should definitely know about the arguments FOR this very common and established open source platform.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
