What can I do with the esp-01s module?
The ESP-01 module has GPIO pins that can be programmed to turn an LED or a relay ON/OFF through the internet. The module can be programmed using an Arduino/USB-to- TTL converter through the serial pins (RX, TX). Connecting the Hardware to Your ESP8266 We can either use a USB-to-TTL converter or use an Arduino to program the ESP8266.
How to program an ESP module on Arduino?
In this tutorial let us Set up the Arduino IDE for ESP module and program it to blink a LED light. Step 1: If you do not have an Arduino IDE download it and install it from here. (make sure the Arduino Version is 1.6.5 or above) Step 2: Navigate to File -> Preferences to open the below dialog box.
Can you use AT commands with ESP8266 module?
To work with AT commands again you have to flash your ESP8266 module with the firmware, which has been explained below. Most of the time while learning to use the ESP8266 Module we will get stuck somewhere and might want to flash the ESP8266 module so that we can get it back to working again.
Where are TX and RX on the ESP-01?
Note that TX and RX from the ESP-01 are now connected to pins 7 and 6 correspondingly. Now that we have the setup complete, we are going to control the LED via Wi-Fi to turn it ON or OFF. We are also going to check to make sure that when the button is pressed that a message is received about its change of state.
How to test and work with ESP-01 module?
After flashing, you can use AT commands to test and work with the ESP-01. Download the official ESP8266 AT instruction set: https://www.espressif.com/sites/default/files/documentation/4a-esp8266_at_instruction_set_en.pdf Extract the Flash Download Tools zip file and open the exe file.

Can You Program ESP module using Arduino IDE?
We have also made a development board, using a FTDI Serial Adapter Module, which can be easily used to program the ESP module using both using AT commands and Arduino IDE. Before we get started, let me tell you why we need to learn the above things.
How to connect the ESP module to the breadboard?
The Arduino UNO is used to provide 3.3 V power directly to the ESP module’s VCC pin. Connect the 3.3 V pin to the breadboard using a jumper wire, since the 3.3 V will be used not only for the ESP’s VCC pin but also the ESP’s CH_PD pin to enable the ESP chip.
