Frequently Asked Questions

1.How to connect an ESP8266 ESP-12F with Arduino Mega?
The Arduino has a microcontroller chip(AVR family) and the ESP8266 has a microcontroller chip. It can use UART peripheral to get the job done. General Instructions: 1.ESP8266 has 3.3V tolerant pins, It might damage the WiFi module if people try to power it using 5V. 2.ESP8266 requires more current when it is at full capacity. More current than what the Arduino can give, It suggests using a separate power supply for ESP. 3. Arduino TX and RX pins are of 5v, use a level shifter (voltage divider) to convert it to 3.3 V, and then connect Arduino TX to ESP RX and vice versa. (Note that then people can't use Serial module for PC debugging, also people have to power up Arduino using a 9V adaptor). 4. ESP understands AT commands. See the documentation of ESP, we'll find those commands there. eg. If people do this from Arduino: Serial.println("AT"); It will get an OK response from ESP. People can use SoftwareSerial functionality also, which can send commands from PC to Arduino to ESP.
2.What are the features of ESP8266?
ESP8266 is high integration wireless SOCs, designed for space and power-constrained mobile platform designers. It provides unsurpassed ability to embed Wi-Fi capabilities within other systems or to function as a standalone application, with the lowest cost, and minimal space requirement.
