Pinout diagram of the Arduino components (Flash Mode)

Pinout diagram of Arduino components. This pin structures enables to init the ESP8266 module in Flash Mode to load code. The upper section of the breadboard is dedicated to the ESP8266 module pins, which is powered by a 3.3V voltage and uses a 10k resistor. The voltage flow to the WiFi module is controlled by the green pin connected to the breadboard in the last column of the positive charge row. The lower section of the breadboard is almost completely dedicated to the DHT temperature sensor. This sensor works with a voltage of 5V and a resistance of 1k.

Pinout diagram of the Arduino components (Boot Mode)

Pinout diagram of Arduino components. This pin structures enables to init the ESP8266 module in Boot Mode, executing the loaded code and sending data. After the instructions have been loaded, connect the GPIO0 pin (white) of the ESP8266 module to the voltage across the resistor. In this way, the ESP8266 module will not enter the Flash Mode the next time the Arduino platform is started, allowing it to execute the loaded code as soon as it receives power. Besides, the DHT sensor blue pin transfers the output signals, which must be captured by the WiFi module through the GPIO2 pin (blue).
