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 ...
If you want to use LoRa with an SBCs like the popularRaspberry Pi 4, or an Arduino microcontroller like theWio Terminal, the Wio E5 Grove module will be your best bet. Featuring full LoRaWAN capabilities in the modular simplicity of theGrove ecosystem, the Grove Wio E5 lets you bring y...
UncleRuswho provides well maintained collections of driver components for ESP32 underhttps://github.com/UncleRus/esp-idf-lib. I tookDHTlibrary from there. Sure enough it worked out of box. winlinwho provides simple and trouble-freeSimpleDHTArduino library to read DHT temperature sensors (includi...
Introduction: How to Make RGB Lighting Clock🌈 Neon Color Changing Wall Clock Using Ws2812 LEDs, DS3231, DHT11 and Arduino UNO 1 Step 1: Hi guys, today this project we using Arduino UNO, and get the real time via DS3231 clock module, get temperature via DHT11 sensor. And then, let...
This library is super handy and lets us connect to a WiFi network, but also create a WiFi network if we want.Start your Arduino sketch using:#include <SPI.h> #include <WiFiNINA.h>The SPI library is used by the WiFiNINA library, so load it as well. SPI stands for Serial Peripheral ...
I used theESP32 3.2" LCD Touch Screenas the other client to subscribe the message of sensor data. ESP32 3.2’’ LCD that runs the MQTT client library of Arduino can be a client to communicate with the MQTT broker through WiFi. And it has an LCD to display the subscribed message. Besid...
Once the Keypad library is installed, you can upload this code to the Arduino if you’re using a 4X4 keypad: #include <Keypad.h> const byte ROWS = 4; const byte COLS = 4; char hexaKeys[ROWS][COLS] = { {'1', '2', '3', 'A'}, ...
I tested the setup of the Wifi Scanner. In the Menu of the Arduino IDE, I went to to File > Examples > ESP8266Wifi and select WiFiScan. I installed the libraries for the weather station: Sketch > Include Library… > Manage Libraries… ...
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) ...
January 2025: CarnotCycle is pleased to note that Leonid Alekseevich Molev, a 5th grade student at Lyceum No.8 in Voronezh in southwestern Russia, was awarded a diploma for his Computer Science research project “Arduino platform basement ventilation system” submitted in summer 2022. ...
