This idea came to me last year.ı want to send a tweet with talking and ı tried almost one day ,but ı didnt.And last week , idea came to me again.And ı have one esp8266 module , yes ! ı can do it , and started to try again.

The following setup could be done under $20. Firstly you need api key for connect to twitter.I use thingspeak api key.now you must sign up at thingspeak web site.And than clicks app , then click thingtweet. you can see your api key.

Step 1: Material and Connections

We need

BUTTON
RESISTOR

button is connected as pull down -->arduino 12

VCC 3.3V(NOT 5V)

GND GND

TX RX

CH_PD 3.3V

Bluetooth HC-05 ARDUİNO

VCC ---------------------5V

Step 2: Coding

On the Android device i use an Application called as AMR_Voice to convert voice into string of data and send it over bluetooth. You can download this app from Google Playstore by clicking here.

if you want to make android app , you can make with app invertor.app invertor included media to convert voice into string of data.
