The purpose of this repo is to give you a working example of writing an Android app to run an ESP32. My project is a small car that has a DC motor with a servo for steering. The ESP32 is equipped with a small OLED display so you can easily see what IP address to connect to, and which post to use.

The other version, NO-OLED, uses a standard serial monitor to replicate the OLED display for those who use a regular ESP32.
