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.
