What are the 3 modes of ESP8266?
The ESP8266 has three modes; mode 1 which is “Station” mode, mode 2 which is “Access Point” mode, and mode 3 which is “AP + Station” mode where the device can act as a WiFi client and access point simultaeously.
Why ESP8266 is used?
The ESP8266 module enables microcontrollers to connect to 2.4 GHz Wi-Fi, using IEEE 802.11 bgn. It can be used with ESP-AT firmware to provide Wi-Fi connectivity to external host MCUs, or it can be used as a self-sufficient MCU by running an RTOS-based SDK.
Which microcontroller is used in ESP8266?

Can ESP8266 work without Arduino?
You can, as said, ESP8266 is a standalone controller module integrated with WiFi. You can use the serial converters like FTDI, CP2102, PL2303 etc. but you have ad some voltage divider and filters circuit to it. (Google them you will get the schematics).
What is the range of ESP8266?
The module has a wireless WiFi transceiver operating in an unlicensed frequency range of 2400-2484 MHz in the IEEE 802.11 b/g/n standard, with support for TCP/IP communication protocol stack and WiFi security including WAP3.
Does ESP01 have I2C?
The SDA and SCL lines of the I2C bus come from GPIO0 and GPIO2 of the ESP-01 (respectively), they are connected to PCF8574 SDA pin (#15) and SCL pin (#14). Two pull up resistors of 10k are required for the I2C bus (pulling up the SDA and SCL lines will not do any damage to the ESP8266EX chip).
What is esp01s?
The ESP-01S ESP8266 WiFi Module is a self-contained SOC with integrated TCP/IP protocol stack that can grant any microcontroller access to your WiFi network. The ESP8266 is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor.
How does ESP8266 connect to WiFi?
Initially when you power up your ESP8266 module you will see it as an access point, which you can then connect to it using wither your smart phone or computer device. Then you can configure the WiFi credentials and connect it to your local WiFi network using the web interface.
Can we connect ESP8266 to my computer?
To see if it works, open the Wi-Fi settings on your computer, look for a network called “ESP8266 Access Point”, enter the password “thereisnospoon”, and connect to it. Then open a terminal, and ping to 192.168. 4.1 (this is the default IP address of our ESP AP). You’ll see that the ESP responds to your pings.
Is ESP8266 a microcontroller?
The ESP8266 is a low-cost Wi-Fi microchip, with built-in TCP/IP networking software, and microcontroller capability, produced by Espressif Systems in Shanghai, China.
How many pins are in ESP8266?
17 GPIO pins
ESP8266 NodeMCU has 17 GPIO pins which can be assigned to various functions such as I2C, I2S, UART, PWM, IR Remote Control, LED Light and Button programmatically. Each digital enabled GPIO can be configured to internal pull-up or pull-down, or set to high impedance.
Which software is used to code ESP8266?
The ESP8266 is a low-cost WiFi module built by Espressif Systems. Its popularity has been growing among the hardware community thanks to it’s nice features and stability, to the point that it can be easily programmed using your Arduino IDE.
Is ESP8266 5V tolerant?
As the ESP8266 is 5V-tolerant, […] there shouldn’t be any issues, however I haven’t had time to test this for longer periods of time. Therefore, if the ESP burns out after a while, just add a voltage divider or something.
What is I2C protocol?
I2C stands for the inter-integrated controller. This is a serial communication protocol that can connect low-speed devices. It is a master-slave communication in which we can connect and control multiple slaves from a single master.
What is wire begin?
The begin() method is used to initiate the TWI as a Master and the begin(address) method is used to join the TWI bus a slave using the address specified. In both cases the begin method must be must be placed in the setup() method. Syntax. Wire. begin()
What is the difference between ESP 01 and esp01s?
The ESP-01 includes two LEDs near the PCB antenna, one for the Tx line (GPIO1) and the other for the power indicator. The ESP-01 S, on the other hand, has only one Blue LED and is wired to GPIO2. Two more pull-up resistors were added to the ESP-01 S, which can be seen between the ESP8266EX chip and the header pins.
What is the maximum voltage of the ESP8266?
3.6V
The ESP8266’s maximum voltage is 3.6V, so the Thing has an onboard 3.3V regulator to deliver a safe, consistent voltage to the IC. That means the ESP8266’s I/O pins also run at 3.3V, you’ll need to level shift any 5V signals running into the IC.
