- Download the Arduino Environment. You can direct download the latest version from this page: When the download finishes, unzip.
- To program the Arduino with the Raspberry Pi I needed to install the Arduino IDE on the Kano Computer (make sure you're connected to the Internet thru WiFi). On the Kano desktop, I opened apps, then.
As an open-source electronics platform, Arduino circuit boards are very popular for IoT projects. While the standard way to use them is to hook up Arduino USB ports to a computer, you can also do it using Bluetooth controllers and Android apps.
Program Arduino with ease! This thoroughly updated guide shows, step by step, how to quickly program all Arduino models. Programming Arduino: Getting Started with Sketches, Second Edition, features easy to follow explanations, fun examples, and downloadable sample programs. Discover how to write basic sketches, use Arduino’s modified C. Learning to code embedded hardware usually takes years of formal education. Alongside a good understanding of the electronics involved, programming microcontrollers requires a high level of coding knowledge. Beginning C for Arduino, Second Edition is written for those who have no prior experience with microcontrollers or programming but would like to experiment and learn both. Updated with new projects and new boards, this book introduces you to the C programming language, reinforcing each programming structure with a simple demonstration of how you can use C to control the Arduino family of.
In case your computer is not available for powering up Arduino boards, an Android phone is the best available option.
You will need the following components to prepare this setup:
1.OTG Cable: a standard OTG cable with USB 2.0 for older Android phones. For the latest smartphones which have Type-C ports, you will need an OTG cable with Type-C ports.
2. Data transmission cable: a data transmission cable with Type A USB 2.0 Male to Type B USB 2.0 Male for further connections.
3. Arduino Uno board: you may use any other Arduino boards.
4. LED: this will be used for testing the connection. You can also use a servomotor or whatever else you need to test.
5. Arduino Android app: while there are quite a few decent apps, it is relatively easy to work with ArduinoDroid. It is a heavy app (210 MB), so you need a decent amount of space in your phone memory. Moreover, the app cannot be written to an SD card.
6. Miscellaneous: you will also need a breadboard and some connector cables to connect with it. A few resistors are necessary to divide the voltage.
How to Assemble
The Arduino-Android assembly setup is very simple and does not require too many steps.
- Connect the USB Type-A male plug to the female USB of the OTG cable which further goes to the smartphone.
- Connect the USB Type-B plug to the Arduino board.
- Use the connector cables to join the LED on the breadboard to the Arduino Uno board. The precise position of the connectors on Arduino Uno is determined by the code provided by the app. (See the next section for that.)
An approximate assembly should look like the one in the above picture.
Using the ArduinoDroid App
After downloading and installing the app on your phone, go to the home screen and click the three-dot menu icon.
Next, go to “Settings,” followed by “Board Type” and “Arduino.”
In the next step you must choose “Uno” as the board type. Depending on the type of Arduino board you’re using, you can choose from many other options.
Again, go to the three-dot menu and select “Sketch” followed by “Examples.” There are a great number of examples. For LED lights, you just have to go to “Basics” followed by “Blink.”
Automatically, the code for LED blinking is visible on the Editor screen.
The code says that the Uno board should be attached to digital pin 13. Go back to the previous section, “How to assemble,” to insert the LED connector cable to digital pin 13 on the Arduino Uno.
Another connector will go from the Arduino Uno ground pin to the LED on the breadboard, as will the resistors.
In the below image, you can see a “flash” sign, which is the compiler. Just click it and the LED blinking program starts compiling and loading to the Arduino Uno board.
Once done successfully, you can control the LED light directly from your Android phone. You can look for many other project examples in the libraries of ArduinoDroid, which include servomotors, temperature and pressure sensors and such.
Learning how to manage and control your Arduino projects from your Android phone is easy and requires just a little attention. Solidworks serial number location. Of course, you can find further guidance on this topic at the Arduino official forum and this site as well.

How do you program an Arduino using a Windows PC? This blog will tell how. But before we get into that, let’s take a look at what is an Arduino?
What is Arduino?
An Arduino is basically a single board microcontroller that is used for building digital devices and interactive objects that can sense and control objects in the physical and digital world. These Arduino boards are available both in preassembled form or as do-it-yourself (DIY) kits. Arduino board designs use a variety of microprocessors and controllers. The boards come fitted with sets of digital and analog input/output (I/O) pins that can be interfaced to several expansion boards or breadboards (shields) and other circuits.
One of the biggest advantages that Arduino boards have over Raspberry Pi is the fact that they can read sensitive values from sensors and Arduino boards have analog input and output and not digital input output which is the case with Raspberry Pi. So in some instances where exact values are needed - say, if you want to measure the exact soil moisture, then Arduino is a better bet because it can read analog values as opposed to the Raspberry Pi which will need another chip to read analog values.
In this blog, we shall look at how we can program an Arduino board using a Windows PC. Here’s the step-by-step process to program an Arduino board with a Windows computer:
Downloading and installing Arduino on a Windows PC
Step 1: Get all the needed equipment in place. This means having with you the Arduino Uno board and the USB data cable that will help you connect the board to your Windows PC.
You’ll also need a breadboard, jumper cables(M-M), an LED and a resistor (with a resistance of say, 330 Ohms).
Step 2: Then start by connecting the narrow end of the USB data cable to your Arduino board as shown below.
Step 3: Then connect the other end of the USB data cable to your Windows PC. At this stage, your PC and the Arduino board have been connected to each other using the USB cable. The connections will look like it is shown in the image below.
Step 4: Now go on to download the Arduino IDE on your Windows PC. To do this, just search for Arduino on Google. Now select the Arduino IDE link. On the right hand side, you can see the Windows OS Installer that we can use. There’s also the Mac OS X Installer. In this case, we choose the Windows Installer and complete the setup. That’s when it begins to download your computer. Once it downloads, one can run the Installer in the next step.
Step 5: To install the IDE, we need to run the file that we just downloaded. Click on Agree and continue with the default settings for the rest of the installation. Once the installation is done, click on the close button to finish the installation.
Now that we have downloaded and installed the Arduino IDE on our Windows PC, we can carry out a number of tasks using the Arduino IDE. This includes getting the board to say, “Hello World”, running the counter program and lighting an LED - all using the Arduino.
Saying “Hello World”
Let’s look at what goes into writing our first program, the “Hello World” program. Let’s open the Arduino IDE that we have installed on the computer. Make sure you check the board name under the Tools option as Arduino Uno. Also make sure that the communication port is selected as COM3. Now to see the information sent by our Arduino, we have to open the serial monitor we see on the right.
In the program, we start by putting Serial.begin 9600 in the void setup function which is the one-time setup required for exchanging information over the serial port from the Arduino to the computer. 9600 here is called the baud rate. It is the rate at which the Arduino can send symbols or characters to the computer.
In the void loop function, we use a very simple serial.print to show data on the serial monitor.
You can first save it and then upload the design onto the Arduino. You’ll then see that the words “Hello World!” are being sent by the Arduino to the computer and we can see the words on the serial monitor. You’ll see that the words “Hello” and “World” are appearing next to each other. However, if we use a n in our print command, we will see the two words printed one below the other.
Running the Counter Program
Let’s take a look at the next program. We will design a simple counter by opening the Arduino IDE and the serial monitor. Let’s start by defining the counter variable. Here we say int <space> counter equals one and add a semicolon at the end. This initializes the value of the counter to 1 at the beginning. Now just like in the previous program, we initialize the serial connection.
In the loop, we print the counter value and we also increase the value of the count by one. Here, we use the printIn function to automatically add a new line after having printed the value of the counter. Now this would be too fast and for us to understand what’s happening in the output, we add a delay and the argument is in milliseconds. So for a one second delay, we provide an argument of thousand to the delay function. Finally, increase the value of counter by one using the counter++ statement. Once we save and upload this design onto the Arduino, we will be able to see that a counter variable is constantly being increased in value and this value is being communicated to the computer over the serial connection.
Lighting an LED
Lighting the inbuilt LED on the Arduino
Now the next program we will be working on is blinking the Arduino’s inbuilt LED. You can see that right next to pin number 13 among the digital pins, there’s an LED which is orange in colour. We will learn how to make it blink once every second. And just like we do with the Raspberry Pi, we will start by initializing the pin to be an output so we can control its values. Here we say pinMode and we say 13 which is the pin for the inbuilt LED and we set it as an output so that we can send values of high or low. We then begin our loop function by setting value of the 13 pin to 1 (or high). We do this by using the DigitalWrite function. We then add a delay of one second and then we set the value of the 13 pin as low. Don’t forget to add a delay after turning it low. Now when you run the code, you should be able to see the light next to the pin number 13 blink.
Program Arduino Ide
Writing the program to blink an LED on the breadboard
Here we will see how one can write the program that allows the Arduino to make an LED on the breadboard blink once every one second. Just like in the previous case, we will set values and this time, we will choose pin number 12 and we will set it as an output. So we type the pinMode, 12, output. In the void loop, we use the serial to communicate messages from the Arduino to the computer. We use the DigitalWrite function to turn the pin on or set it to high. Then we add the delay of one second. In the same fashion, we will turn the pin off by using the DigitalWrite function. Similarly, we can add a message and a delay so that we see the output very clearly.
Next you can save and upload this. Go to your Arduino, make sure you have the serial monitor open so you can see the output. Now this code seems to work as it prints LED high and LED low every one second. At this stage, we need to make an LED circuit on the breadboard and connect it to the Arduino to see the actual result.
Making connections to blink an LED on the breadboard
Now we will explore the connections to be made on the breadboard so as to make an LED blink from the Arduino.
Program Arduino In Assembly
Here’s how you make connections to blink an LED on the breadboard using an Arduino:
Just like with Raspberry Pi, we set up the LED first. We place the LED on the breadboard across the middle separation.
Then we add a resistor (say with a resistance in the range of 220 to 600 ohms). We place one end of the resistor on the same line as the LED.
Now we connect the resistor’s other end to the railing for the Ground.
We use a wire to connect it to the Ground pin on the Arduino.
The closeup of the Arduino after the connections have been made will look like this.
We then connect the other end of the LED to the pin number 12 which we are programming for.
The closeup of the breadboard after the connections have been made will look like this.
Since the program is already on the Arduino, we should immediately be able to see the light blink.
