Before you can use the DHT11 on the Arduino, you’ll need to install theDHTLib library. It has all the functions needed to get the humidity and temperature readings from the sensor. It’s easy to install, just
For an illustration of how to assign a static IP address to ESP32, we use the example of anESP32 Web server with DHT11/DHT22. We will use the same sketch use in that tutorial except adding the functionality of assigning fix IP address. In order to understand the code given below, I ...
How to Make RGB Lighting Clock🌈 Neon Color Changing Wall Clock Using Ws2812 LEDs, DS3231, DHT11 and Arduino UNO: 1
The Wire library is needed to add support for I2C communication. It comes packaged with the Arduino IDE, so there’s no need to install it. But if for some reason it’s not installed on your system, go to Sketch > Include Library > Manage Libraries and search for “wire” to install ...
The module (Micro SD-Card Adapter) is a Micro SD card reader module, through the file system and the SPI interface driver, SCM system to complete the file read and write Micro SD-card. Arduino users can directly use the Arduino IDE comes with an SD-card library card to complete the ini...
Add this check to your program:if (WiFi.firmwareVersion() < WIFI_FIRMWARE_LATEST_VERSION) { Serial.println("Firmware upgrade available"); }to know if that’s the case. If so, using the Arduino IDE (I can’t see how to do this from Arduino Create) connect to the board then load ...
Arduino has a detailed walkthrough ofhow to install librariesfor its IDE. And Adafruit hasdetails on the MQTT API. The reed switch does not require a library of its own because you will read whether voltage is present (“HIGH” or a value of 1) or not (“LOW” or a value of 0) ...
DHT11 Sensor Library MQ-135 Sensor Library Adafruit GFX Library Adafruit SSD1306 Library Blynk ESP8266 Library After you add these to Arduino IDE library, the codes will be compiled automatically. However, change theWi-Fi SSID,Password, and theBlynk Authentication Tokento connect the ESP2866 circu...
Open the Arduino IDE. Go to File >> Examples >> Basics >> BareMinimum then upload the sketch. This is to make sure that no program is running on the Arduino board. Next, open the serial monitor. Make sure to set the baud rate to default, which is usually 115200. Then, type the ...
