To upload your code to the ESP8266, the module must enterFlash Mode, which is achieved by holdingGPIO0LOW (connecting it toGND) and resetting the ESP8266. You can reset the ESP8266 by momentarily grounding theRESETpin (you can attach a push button between the reset pin and ground)...
The Esplora is supplied with four pushbuttons, a switch-type joystick, and a micro USB connector. Four mounting holes are available to affix the board to a chassis or panel. The Esplora PCB dimensions are shown in Figure 4-13. Arduino Pinout Configurations When creating a shield board for ...
By following these steps, you should be able to successfully upload your sketch to your ESP32 board. You can explore further by looking into these tutorials: ESP32 pinout – How to use GPIO pins? GPIO pins of ESP32 – LED Blinking example Push button with ESP32 – GPIO pins as digitali...
While it is fine to solder all 24 pins to the shield, only the 12 pins required by the reflectance sensor array need to be soldered (see the Array pinout section below for more information on which pins are required). With the female header in place, the assembled sensor array can be ...

As you can in the above pinout diagram of ESP32, we have a total of 36 GPIO pins, but we will be usingGPIO22as a digital output pin. On different boards, these pins can be located at different locations. Therefore, you need to check its datasheet before using pin number in programmin...
