在ESP8266上只有一个ADC GPIO。它的测量范围是 0 to 1V。而NodeMcu基于ESP8266-12,所以也只有一个ADC GPIO,但是由于电阻分压电路,可以测量范围扩展到0-3.3V。 5.4 板载LED灯 NodeMcu上存在一个板载LED灯,目前是连接到 GPIO2。 高电平灭、低电平亮 5.5 复位按键 当按键接到GND,ESP8266复位,系统重启。 5.6 ...
The HX711 amplifier communicates via two-wire interface. You can connect it to any GPIOs of your chosen microcontroller. We’re connecting the data pin (DT) toGPIO 12(D6) and the clock pin (CLK) toGPIO 13(D7). You can use any other suitable pins (check the ESP8266 pinout guide). ...

If you want to learn more about the ESP8266 module, first read my Getting Started Guide for the ESP8266 WiFi Module. This tutorial covers two different methods to build the web server: Part 1: Create a Web Server Using Arduino IDE Part 2: Create a Web Server Using NodeMCU Firmware PART...
Pin numbers written on the board itself do not correspond to ESP8266 GPIO pin numbers. We have constants defined to make using this board easier: staticconstuint8_tD0 =16;staticconstuint8_tD1 =5;staticconstuint8_tD2 =4;staticconstuint8_tD3 =0;staticconstuint8_tD4 =2;staticconstuint8...
Full integration on one board: Mega R3 ATmega2560 and WiFi ESP8266 with memory 32Mb (megabyte) All of the modules can work together or each separately. And everyone has their own pinout headers The convenient solution for the development of new projects requiring Uno and WiFi Via USB you can...
NodeMCU是一款基于ESP32芯片的开源硬件平台,它集成了Wi-Fi和蓝牙功能,可以用于物联网应用开发。在ESP32上启用UART1/2是指在NodeMCU上使用UART1或UART2串口进行通信。 UART(Universal Asynchronous Receiver/Transmitter)是一种常见的串口通信协议,用于在设备之间传输数据。UART1和UART2是ESP32芯片上的两个串口接口,可以...
Last but not least, we connect VOUT and GND to the ESP-01/NodeMCU (here we take the 3.3V pin and GND. ESP8266 ESP-01 Pinout NodeMCU Dev Board Pinout Measure Solar Cell and Battery Voltage with the ESP8266 Depending on the weather and time of year, the battery is charged more or les...
