user14022: I have with me an Arduino UNO and an ESP8266 (12E) WiFi Module. I need to make a webserver using the two. I read that the default baud rate for ESP8266 is 115200, and that the software serial pins can't handle such high speeds. I dont have an USB-UART converter at hand. Is there a way to use my Arduino as one to change the baud rate, so that I can interface with the chip using the software serial pins of the Arduino later.

user29436: You can use this block of code in Arduino to set baud rate...
void setup() 
{
  Serial.begin(9600); // opens serial port, sets data rate to 9600 bps
}

void loop() {}

Change value in serial.begin() as per your value.

user30152: Use SoftwareSerial library for your module and define your own tx and rx pins like this and then you can define baud rate for your specified serial pins.
#include <SoftwareSerial.h>
SoftwareSerial mySerial(8,9); // RX, TX for your module
void setup(){
   mySerial.begin(115200);
}
