Return value is a struct of typeTempAndHumiditywith temperature and humidity as float values. See exampleDHT_Multi.ino DHT_ERROR_t getStatus(); Get last error if reading from the sensor failed. Possible values are: ERROR_NONE no error occured ...
struct tm timeinfo; if(!getLocalTime(&timeinfo)){ Serial.println("Failed to obtain time"); return; } Serial.println(&timeinfo, "%A, %B %d %Y %H:%M:%S"); } void setup() { Serial.begin(115200); //connect to WiFi Serial.printf("Connecting to %s ", ssid); WiFi.begin(ssid, pa...
Next, we use our “accel” object’s “getEvent()” function, passing in the event variable we defined before. This “getEvent()” function will retrieve data from the accelerometer and fill out the struct that we pass into it (In this case the “event” variable) with the relevant data...
In this tutorial we are going to build a Cough Detection system using Arduino 33 BLE Sense and Edge Impulse Studio. It can differentiate between normal background noise and coughing in real-time audio.
We will start the implementation of the FreeRTOS function by declaring a struct of typesh2lib_handle, which will be used in the nextsh2libfunction calls. struct sh2lib_handle hd; Then, we will establish the connection to the HTTP2 server by calling thesh2lib_connectfunction. As first inp...
In this work, the Android Bluetooth Controller App created by55 is installed on an Android cellphone. An HC-05 module serves as a medium for communication between Arduino and the Bluetooth Controller App. When the predefined key on the app is pressed, the corresponding data is sent to HC-05...
In your Arduino IDE, go toFile>Examples>ESP32>Camera>CameraWebServer. Then, modify the code to act as an access point as we’ll explain. Customize the SSID and Password You need to define an SSID name and a password to access the ESP32-CAM access point. In this example we’re settin...
Thus, as long as in the thread function we cast the variable back to int, we can correctly obtain its value. Note however that this cannot be done if the size of the variable we want to pass to the thread is greater than 4 bytes (for example, a struct) and in that case we need...
There are various types of displays that come all with the same Hub75 connector. They vary in the way the multiplexing is happening so this library supports options to choose that. All these are configured by flags (or, programmatically, in anOptions struct). ...
Prepare the UserData property to store the Arduino data. In this case, define UserData to be a struct in which the Data field contains sine wave values and Count records the number of data points collected. This structure allows for organized and efficient access and updating of these related ...
