ESP8266 wifi module

i set up my module as shown.
On tutorials, after the hardware setup (while leaving power leads disconnected) they opened the console window on a blank sketch. "Carriage return" and a baud rate of '115200' were chosen. afterwards they connected power to the module, the module started outputting characters as sort of a "device is recognized" acknowledgement.

following these steps, when i power on my module, nothing prints on my console window.
when i send a command, the blue light blinks, but other than that nothing happens.

You need an external 3.3V supply. The 3.3V regulator on an arduino (or an ftdi breakout) is insufficient.

current capacity?

hooked up an external 3V supply. same thing, nothing was outputting on screen.

i should mention, earlier i somehow got the module to output "READY" by taking the arduino RX line and replacing it with the ardduino TX line. after the "READY" i was able to issue AT commands

any ideas.. guys?

Is the black wire in your drawing connected to the yellow wire? You might be able to communicate directly with the ESP8266 from the arduino serial monitor if the arduino/ESP8266 tx are connected together, the arduino/ESP8266 rx are connected together, and the arduino/ESP8266 grounds are connected together (with serial monitor and ESP8266 set for the same baud rate).
