Introduction: More GPIO for ESP8266 - 01
The esp8266-01 module has a lot of applications programming either in company with arduino, or by programming only from the Arduino IDE interface.
This module is ideal for applications via wireless data transmission and the cost is the best unlike other costly inhalambricos modules. Since the ESP8266 - 01 only has 2 GPIO available,
I was forced to get another gpio, carefully perform welding on pin 14

Step 1: Knowing Arduino IDE
Installation and configuration of Arduino IDE for programming ESP8266 Module - 01
Step 2: Components and Materials Required for Testing
1 Soldering iron with fine tip
1 wire thin copper
select pin 9 or GPIO 14
select GPIO pin 9 or 14 since it was the easiest position to be soldered copper wire.
Step 3: Testing...
classic blink test is performed and works very bn our new GPIO
If in the future there is a need soldare more pins ....
We have a be nice policy.
Please be positive and constructive.
