PROJECTS

Project 1. Make a Home-made Network Clock with ESP32-E

Introduction: This production will be very simple, getting the time from the

internet via the wifi of the ESP32, and then you need to find a screen that

displays the time. There are many options for the screen, LCD1602 or LED

monochrome dot matrix for splicing. I accidentally saw a VFD fluorescent

screen before, it was green-blue when it was lit, and it glowed with white light,

which makes the whole screen a mottled beauty. So, I am going to use it here.
