ESP8266 Arduino Tutorial 2 – Create the First Program

Posted on by Erwin Ouyang

Driver Installation

In the previous tutorial, the Arduino IDE has been installed. In this tutorial, we will create the first program. This program uses the on-board LED on ESP-12E module. The LED will blink every 1 s. Before we go to the programming, we must install the NodeMCU USB driver. The step-by-step how to install the NodeMCU driver is described as the following:

  • Download NodeMCU driver from this link.
  • Connect NodeMCU board to the USB port.
  • Run the driver installer file: CH341SER.EXE, and install the driver.

ESP8266

ESP8266 is a low-cost Wi-Fi System-on-Chip (SoC) produced by Espressif Systems, a Shanghai-based Chinese fabless semiconductor company. The ESP8266 chip is shown in the following figure. It consists of a Wi-Fi transceiver with full TCP/IP stack and a microcontroller. It uses IEEE 802.11 b/g/n Wi-Fi standard, which is generally used in our daily life. It has 32-bit Tensilica RISC processor that runs at 80 MHz. It has several peripherals such as GPIO, I2C, SPI, UART, ADC, etc.
