Check the following diagram for the complete wiring: (Download the Fritzing source for the wiring diagram HERE.) An interesting post showing how to flash the ESP8266 using an Arduino instead of the USB to serial converter (used in the graphic above) can be found HERE. To flash the ESP8266 MicroPython Firmware, make sure that the flash tool is installed (or if installed, is up to date): Install ...
Circuit Diagram for Flashing the Firmware to ESP8266. The following image shows the circuit diagram for enabling the Flashing Mode in ESP8266. In order to put the ESP8266 SoC in Flashing Mode, the GPIO0 Pin must be connected to GND and a momentary GND Pulse on RST Pin. Components Required. Arduino UNO ESP8266 ESP-01 (any ESP8266 Module)
So, we can wire something to the RST pin and use it as an external wake up. It can be the press of a pushbutton or a magnetic reed switch being close, for example. The ESP8266 resets when the RST pin goes LOW. Schematic Diagram. To test this method, wire a pushbutton to the RST pin. You need the following components for the circuit:

In this illustration we will going to wire the ESP8266 12E nodeMCU with Ultrasonic Raging Sensor HCSR04. As you can see the illustration below the sensor trigger pin is connected to D1 which is pin 5 in Arduino Board, and the ECHO is connected to D2 which is pin 4 in Arduino Board.

When you buy the ESP8266 ESP-01, it comes with a pre-installed AT firmware.It is possible to program the chip with another firmware such as NodeMCU, for example.However, AT firmware is compatible with the Arduino IDE, so we are going to use this firmware for this tutorial.If you want to know how to install a different firmware, then read the Miscellaneous section in this tutorial.
