First of all it is great a pleasure for me to finally join in this illustrious community. I have found out about Platformio project on January of this year and ever since have been using it for many of my arduino projects. I use the Atom Text editor which I found to be extremely easy and intuitive to learn and use.
When I write codes in Arduino IDE, I can split the function bodies from the main ino files into discrete files following a sequential alphabetical naming scheme viz. A.main , B.pid, C.motor etc etc. When I hit the compile button, arduino compiles all these files and their associated header files without any error. Also the other ino files are capable of recognizing public variables, function calls written in libraries by other users installed into the Arduino IDE.
But in platformio, say I make the above files as such, main.cpp, pid.cpp, motor.cpp numerous errors are thrown including missing variable declarations from other libraries, for instance tft declaration of Adafruit GFX library is not recognized in other cpp files EXPECT in the main.cpp file.
Hence though I am not an expert in this subject matter, I strongly believe the platformio community/team should make ONE DEFINITIVE TUTORIAL to teach us less experienced programmers on how to create a multifile arduino project which will do the following
And a header-file (.h) with the function prototype and the struct definition. Arduino.h has to be included so you can use the variable type String. To clean up your project directory you can put the header-file in the include-folder while the source-file (.cpp) should be in the src-folder.
myhelperfunctions.h:
I totally agree. My programming discipline is questionable. I have a lot of multiple .ino projects and I am having a real struggle with getting a clean and manageable structure in Platformio.
At the moment, the Arduino IDE makes them far more readable.
For native C++ programmers, I guess the structure is second nature. For migrants from Arduino, it needs a better explanation - please?
I found that once I had a project working in platformIO that it was easy to navigate to, say a function, because they are all listed. However, I went back to the Arduino IDE for now because I can be get the job done much easier and quicker.
When I next try platformIO I plan to move the code from multiple tabs into one main tab, import that to platform.IO and get it running then maybe break it down into separate .ccp and .h files.
The Arduino microcontroller has a nearly limitless array of innovative applications for everything from robotics and lighting, to games and gardening! It's a fun way to automate everything, enabling you to control simple devices or manage complex Halloween displays.
Here are some of the best do-it-yourself Arduino technology projects to educate and inspire you to make great things!
I have a #include "folder/foo.h at the top of project.ino. However while the header provides the prototype of the function, the function definition is in the cpp file. When I try to compile the code using the Arduino IDE, it fails with errorUndefined reference to 'bar()'and bar() is located in foo.cpp
Next, I used Eclipse to start tracking down includes, to see where Serial gets pulled in (it should have been obvious to me already what the problem was, but I didn't see it yet). I found the following:
Now, go there and create a "libraries" folder. For me that would now be /home/gabriel/dev/Arduino/Sketches/libraries. Everything inside this folder is now considered an Arduino "library", and can be included. Move foo.h [do NOT use foo.hh in this case] and foo.cpp there, like this:
The reason you can't use foo.hh in this case is simply because Arduino is looking for .h files only when you add your library include using the menus in this way. That's a bug as far as I'm concerned, and should probably be reported to the Arduino developers. Feel free to take that on.
Open a tab in your project for each file.You can create a new file or import an existing file into your project.This way you can use multiple *.ino, *.c, *.cpp and *.h files. I didn't find a way to import a local directory or to configure your project structure.
This project describes how to make an alarm clock radio in Arduino. The main feature of this project is that it will display the date and time and will Alarm at the desired time and it has a radio function too.
Presented here is a window alarm annunciator based on an Arduino Uno board. An annunciator is mainly used in process plants, power plants, and industries to monitor various plant conditions to alert operators about abnormal conditions or parameter deviations.

ESP8266 contains a built-in 32-bit low-power CPU, ROM, and RAM. It is a complete and self-contained Wi-Fi network solution that can carry software applications as a stand-alone device or connected with a microcontroller (MCU).
This article represents an Arduino-based digital IC tester that is highly capable, highly reliable as well as cost-effective. Here, we develop a program with different functions for checking different ICs.
Here we present a simple Arduino-based RF-controlled robot that can be driven remotely. This robot can be built very quickly on a small budget. The RF remote control provides the advantage of a good controlling range (up to 100 meters with proper antennae) besides being omnidirectional.
The fancy lights controller described here is built around the Arduino (an Open Source single-board microcontroller) platform that can be purchased in pre-assembled hardware form. The circuit is nothing but a portable four-channel, multi-mode digital light controller, realized using very few external components. Four LEDs are made to glow in different sequences and patterns, controlled from the Arduino board.
Here we describe how you can make your own oscilloscope at a very low cost using your PC and an Arduino board as the hardware for signal acquisition. You can use this oscilloscope to capture frequency signals up to 5kHz. The Arduino board, the heart of the oscilloscope, reads the values from its inbuilt analog-to-digital converter (ADC) and pushes these to the PC via a USB port.
The IoT using Arduino microcontroller (MCU) is easy and fun for those who are new to the field. Presented here is humidity and temperature monitoring using Arduino. In this article, humidity and temperature information from the DHT-11 Humidity and Temperature sensor is analyzed graphically on the ThingSpeak platform using Arduino MCU and ESP8266 Wi-Fi module.
This project is a simple and exciting plant watering system that you can build yourself in just a few hours. With efficient use of a moisture sensor and downloadable component layouts and source code, this could fit in perfectly for potted plants, be it on your terrace or the balcony, or the front lawn. It works everywhere.
If the motion is violent enough during an earthquake and crosses a certain threshold, a local alarm light (LED) glows, a buzzer sounds and a relay energizes. With certain modifications, this can be turned into a knock-and-shake detector for ATMs, vehicles, or door-break alarms as well.

I had a two way switch sitting around that I thought would add to the aesthetics of my pumpkin. If you are going to make a halloween Arduino project, you might as well make it look electronic. Cut out the shape you think you will need somewhere on the pumpkin body.
I should have set up one LED, made sure the length would be sufficient, and then gone and cut the others. That is what I recommend you do. If you cut them too long, then stuffing all the stuff in can be tougher, but you can always cut them shorter.
Whatever method you use, you will then need to connect all these ground wires to the ground on your Arduino. I did this by soldering on an additional piece of hookup wire to the anode of the LEDs and using this to connect all the grounds.
A list of URLs to the package.json files containing this information is maintained in the Arduino preference pages. These metadata files are provided by board vendors and an unofficial list can be found on the Arduino wiki.
There is an equivalent for Libraries though in this case, the Arduino IDE providers maintain the complete list and the Arduino C++ IDE references it directly. This includes libraries for various peripherals like NeoPixels or Wifi chips as well as libraries for reusable functionality like the MQTT protocol.
