“I want to use phone to control the LED board as a turning signal. So, the ESP8266 will act as an Access Point, microcontroller and also a server. The web server will have a simple webpage with 3 buttons: Turn LEFT, Turn RIGHT, and Turn SOS. The text will scroll on the LED boards. For the code, Ive test two well maintenance libraries which are Arduino Core WiFi and ESP8266WebServer. The Core WiFi does not have good request handling function. So I need to use client.readStringUntil(\r) to read request and it is very slow. Then, I switch to ESP8266WebServer library and it runs well.”
