GPIO6 to GPIO11 GPIO14 GPIO15 Interrupt Pins All above-mentioned GPIO pins can be configured in interrupt mode to detect positive edge, negative edge, or level triggered. For more information refer to the following article: ESP32 Interrupts and Timers with PIR Sensor using Arduino IDE ...
The analog pins allow the board to read signals from an analog sensor, like a light sensor and convert it into a digital value. Even though the primary function of the analog pins for most Arduino users is to read analog sensors, the analog pins also have all the functionality of general...
Grove – DHT11 Temperature & Humidity Sensor Hardware Connection Step 1:Connect the Wio-E5 module directly to the “UART” slot of the Expansion Board. Step 2:Connect the DHT11 into the “A0/D0” socket as shown below. Software Preparation ...
How to assign static/Fix IP Address 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...
