B4R Question How to Connect ESP8266 module to Arduino UNO

[sanjog shakya]

Hi,
I am begineer in using Arduino.I want to connect ESP8266 with Arduino uno to change the RGB led light color through B4A app.Is it possible?
How do i communicate through B4A app to Arduino?
I have found HC-05 , Arduino & Android Example https://www.b4x.com/android/forum/threads/hc-05-classic-bluetooth.66677/#content and want to test through Esp8266.
Any help is appreciated.

What do you need the Arduino Uno for? Connect the leds directly to the ESP8266 board.

Start with this example: https://www.b4x.com/android/forum/threads/esp8266-getting-started.68740/

Just be careful with the voltages of each board - Arduino works with 5V, ESP8266 with 3.3V !

my mistake.
I got to know Wemos itself have integrated wifi module.So i think arduino also must be attached with ESP8266 .I was wrong.
I just want to Connect Via Wifi (Android and ESP8266) and control the led from android.
Best Regards,
Sanjog
