Here, we will be using them on different NodeMCU/ESP32 boards and then connect them all through an ESP Mesh network. An image for the hardware setup is shown below. Programming the ESP8266 and ESP32 ...

Unlike other ESP Development Boards, the ESP32-CAM has no USB connector to connect it to a computer. This might be confusing for beginners when they try to program this development board for the first ...

Some Android phones cannot adjust the volume. We asked for help from the idf-esp project and provided a modification patch. It can be used normally in the idf environment. However, we encountered ...

I used the Arduino core for ESP32 from June 2018. This version is the only one supported by Enterprise wifi networks. The first release version of July 2018 has a problem with connecting to the ...

Connect the other end of the USB cable to an available USB port on your PC. The ESP32 can be used as a central device to establish a BLE connection. Arduino Nano 33 BLE Sense: Similarly, connect one ...

After an introduction that includes a crash course in C programming basics, users get training in how to connect Arduino boards with ESP32 for full web connectivity.

Connect the GND pin of the DHT11 to a GND pin on the ESP32. Connect the DATA pin of the DHT11 to a digital GPIO pin on the ESP32 (e.g., GPIO 4). Step 2: Setup Arduino IDE for ESP32 Install the ESP32 ...

In case you missed it, the big news is that a minimal Arduino core is up and working on the ESP32. There’s still lots left to do, but the core functionality — GPIO, UART, SPI, I2C, and … ...
