Whenever you need to tell your Arduino to change the state of a pin (e.g. to turn on the lights) the user needs to press a physical button or use a sensor. Relying on a human finger press or something like that is fine for many projects, but what if you just want to set up your circuit and access it?
This article will walk you through 6 ways to make your connection Android Device to any Arduino compatible board. Let's dive in.
The first on our list is ArduinoDroid. This app works over USB on the go What is USB OTG? 5 Cool Ways to Use on Android What is USB OTG? 5 Cool Ways to Use it on Android What is USB OTG and How can you use it on Android? We explain the function and the many ways to use it. Continue reading (OTG) to connect your device to Arduino using a USB cable. One of the advantages of USB is that it doesn't require an internet or bluetooth connection to operate.
The app is a fully featured IDE that allows you to code on your phone, upload sketches previously saved in your Dropbox or Google Drive, and make sketches on the go.
The advantages of this app are obvious. Having an IDE on hand is the perfect thing for making quick changes in the field. Plugging in an Android device is less of a hassle than balancing a laptop on hand!
One obvious downside is that entering code on your device may not be particularly convenient, especially if it's a smartphone. This is only a minor problem when compared to the convenience of an ultra-portable way of programming the board without an internet connection.
This is also an inexpensive way to learn the basics of Arduino. Getting Started With Arduino: Beginner's Guide Getting Started: Arduino: Beginner's Guide Arduino is an open source platform for prototyping electronics based on flexible, user-friendly hardware and software. It is intended for artists, designers, hobbyists, and anyone who wants to create interactive objects or environments. Read more. As a clone, the Arduino board and USB OTG cable only cost a few dollars. Perfect for those without frequent computer access!
2. Arduino bluetooth controller
Next on our list is the aptly named Arduino Bluetooth Controller App. This app is less about programming an Arduino while it is running, and more about triggering changes in the uploaded sketch. The app sends data to your board via Bluetooth, so you can send serial data with the push of a button. You need one Bluetooth module for your board, even though the HC-06 The module is widely available and is available for just $ 3 at the time of writing.
For a great introduction to these inexpensive little modules, check out this video from Tinkernut Labs:
Another app is recommended in the video above, although some users report that it doesn't work on modern smartphones. The Arduino Bluetooth controller doesn't seem to have this problem. It's worth noting that the app is downloaded in English rather than Italian as indicated in the Play Store images!
We have already looked into creating projects with Blynk and found this to be an excellent service. Thanks to its flexibility and simplicity, events on your board can be triggered intuitively. Blynk needs an internet connection as it uses its own server. You can use either Wi-Fi or cellular data to access Blynk, which makes it ideal for use with smartphones.
One of the strengths of Blynk is the variety of ways you can connect a device. In addition to support for almost any development board, you can wirelessly connect to the server via ethernet or even connect a computer via USB. The service is well documented and the intuitive use makes it easy to assemble custom controls for your project. The Blynk library for the Arduino IDE takes care of all communication.
If you're the type of person who wants to start your coffee maker from their phone before they get up in the morning, then this one is for you!
Blynk isn't the only service in this space, neither is the highly customizable Thinger.io and the practically limitless but devilishly difficult OpenHAB. Of the three, Blynk is certainly the fastest up and running, despite getting to know OpenHAB. Getting Started With OpenHAB Home Automation On Raspberry Pi Getting Started With OpenHAB Home Automation On Raspberry Pi OpenHAB is a mature open source home automation platform that runs on a wide variety of hardware and protocol protocol neutral, meaning it can work with almost anyone on the market today home automation hardware available. Reading more is a great idea in the long run.
4. Communication from the ground up
Everything we've covered so far uses pre-existing services to help you connect in a number of ways. But what if you want complete control over every aspect of the Android app? Why don't you do it yourself ??
Hariharan Mathavan guides us through the entire process step by step in this comprehensive process. The app created here is only used to open a USB connection, and send serial data back and forth between the app and the Arduino board. This is a great way to get started with Android Studio and app building in general.
This guide will walk you through all of the code required to communicate with your Arduino over USB. You will find explanations for each step. The following tutorial for implementation Bluetooth connection is just as well explained.
There are several ways to build Android apps without coding. How To Build An Android App: Everything You Need To Know How To Build An Android App: Everything You Need To Know If you're looking to build your own Android app, this guide has everything you need to know. Read More Building your own apps is cool, but before you know it, you could have a whole new career opportunity as a Java programmer. Career Opportunities for Java Programmers With an expected growth rate of 19 percent for the 2014-2024 period (according to US Bureau Labor Statistics), the career prospects for Java programmers are indeed excellent.

5. Turn your Arduino into a server
Another way to communicate with your board is to turn it into a small server. This has the advantage that it opens up the possibility of communicating with the board from anything that can navigate to an IP address or make a web request.
This incredibly detailed tutorial from startingelectronics.org requires one Ethernet shield How to connect your board to your home network. Here is a video of it in action:
Don't have an ethernet shield? Fear not, the same can be achieved with a Wi-Fi sign or a Wi-Fi connected board like the NodeMCU Meet the Arduino Killer: ESP8266 Meet the Arduino Killer: ESP8266 What if I told you an Arduino compatible development board with built in WiFi for less than $ 10? Well there is. Continue reading .
If Python is more your thing, the Instructables user metanurb has a tutorial on bluetooth modules.
6. Infrared control
Are you looking for a true wildcard way to talk to your Arduino? Would you like to take full advantage of MacGyver? Then get one out Infrared (IR) receiver from an old stereo or VHS player and use this to talk to your Arduino board!
This method requires an IR blaster to be installed on your Android device. There are plenty of apps out there to take advantage of this feature, although the Mi Remote controller is free and works with many other home appliances.
Once you've installed the app you need to create a simple circuit to “sniff” IR signals. This IR remote will guide you through building the circuit.
While this tutorial uses an old remote control, the process for using an IR beam from Android devices is exactly the same. The availability of the parts makes it a great entry-level project.
This method only works within line of sight. However, this is the cheapest way to wirelessly communicate with your board. Even if you can't clean the parts for it, an IR receiver costs less than a dollar. For a static device like a set of ceiling mounted LED strips, this could be the perfect solution to a simple problem.
Did we miss a tool?
These are some ways to free your Arduino from your computer, although we're sure there are a lot more. Whichever method you use, why not implement it on a cool project like a DSLR shutter release. Make your own DSLR shutter release. Make your own DSLR shutter release. One shutter that you are undoubtedly looking for is a remote shutter release. This allows you to put the camera on a tripod or rest in another location and release the shutter without the risk of wobbling.
