ArduinoJson.h: No Such File Or Directory (Arduino) - CopyProgramming

Question:

I encountered an issue with FirebaseArduino include libraries as I received an error message stating "fatal error: ArduinoJson.h: No such file or directory". Can you suggest any solutions to overcome this problem?

This is my code

#include #include #define FIREBASE_HOST "example.firebaseio.com" #define FIREBASE_AUTH "token_or_secret" #define WIFI_SSID "SSID" #define WIFI_PASSWORD "PASSWORD" void setup() { erial.begin(9600); // connect to wifi. WiFi.begin(WIFI_SSID, WIFI_PASSWORD); Serial.print("connecting"); while (WiFi.status() != WL_CONNECTED) { Serial.print("."); delay(500); } Serial.println(); Serial.print("connected: "); Serial.println(WiFi.localIP()); Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH); } void loop() { Frirebase.setInt("Count", count++); delay(1000); }

Solution:

In case you come across an error saying "No such file or directory", this typically indicates that the library containing the missing file, which is ArduinoJson.h in this scenario, needs to be installed.

The code documentation ideally includes instructions for installing dependencies; however, in cases where the author has neglected to provide this information, you will need to search for the missing library on your own.

The Library Manager index includes several Arduino libraries that can be installed with ease.

Library Manager installation

1. Navigate to Manage Libraries by selecting Sketch from the Arduino IDE menu and then choosing Include Library .
2. Please wait until the download is completed.
3. Enter your search query in the "Filter your search..." box, specifying "ArduinoJson" as the appropriate term in this instance.
4. Browse the search results until you come across an appropriate option, such as "ArduinoJson by Benoit Blanchon," and proceed by selecting it.
6. Click "Install".
7. Wait until the installation process is complete.
9. Click "Close".

In case the library you require is not available in Library Manager, you will have to devote some time to searching for it on your preferred search engine. After discovering and downloading the library, you will have to carry out its installation.

.ZIP Installation

To add a library in the Arduino IDE, go to "Sketch", then "Include Library" and select the appropriate file format ( ZIP Library ). Choose the desired library ( downloaded file ), which must be in .zip format, and click "Open".

The instructions for installing the software necessitate a specific folder structure for the . zip file . However, it is possible that the library author did not provide the correct structure, resulting in an error message stating that the zip file does not contain a library. In this event, performing a Manual Installation of the library will be necessary.

Manual Installation

2. Unzip the downloaded file
3. Explore the unzipped directory until you locate library folder . This should contain a .h file and/or a library.properties file.
4. Move the library folder to {Sketchbook folder}/libraries, which you can locate in the Arduino IDE by going to File > Properties > Sketchbook location. Remember to restart the Arduino IDE for the manually installed libraries example sketches to show up in the File > Examples menu.
