This tutorial of Robo India explains the introduction of ESP-01(ESP8266) and how to set up ESP-01(ESP8266) module in programming mode
1. Introduction
This is a breakout board for popular ESP-01(ESP8266) module operated at 5 Volt.
The ESP8266 is designed by a Chinese company Espressif .It is a simple application and they easy add a connectivity to another microcontroller, which is very limited number of exposed pins
1.2 Hardware required
| S.No. | Item | Quantity |
| 1 | FTDI Basic | 1 |
| 2 | ESP8266 ESP-01 Breakout Board | 1 |
Users can buy ESP-01(ESP8266) from Robo India Shop: https://roboindia.com/store/esp8266-esp01-breakout-board
2. Features
These pins function as follows:
1) Can be programmed using standard 5v FTDI Module.
2) Separate Pin Out for mounting on Breadboard.
3) On board flash and Reset switch.
4) Inbuilt 3.3v Voltage Regulator.
3. How to Set Up ESP-01(ESP8266) in programming mode
Connect the FTDI to your PC through a USB port. The red led of the ESP module will switch on.
The button on the side of the breadboard is reset button, while the other button is the is GPIO0.
1) Press the reset button and keep it pressed
2) Press the GPIO0 button and keep it pressed.
3) Release the reset button
4) Release the GPIO0 button
If a blue light will switch on momentarily on the ESP module, then your ESP is in programming mode.
4.Upload Your Sketch
1) Open the Arduino IDE.In the Arduino IDE, under Tools –> Board, select “Generic ESP8266 Module”
2) Select the port in which the ESP module is connected.
3) Upload an empty sketch to your ESP module and check if the progress of uploading is displayed in the console of the Arduino IDE .If so, you can now write any sketch you want and program your ESP8266 easily.
