The schematic has two buttons. The sleep button will put the ESP32 in deep sleep mode and another switch is used for waking up the ESP32 from sleep mode. Both buttons are connected in PIN 16 and PIN 33. Both buttons are configured as active low when pressed; therefore an additional pull-up is given. However, to detect whether the ESP 32 is in sleep mode or normal working condition mode, LED is connected to IO Pin 4.
Plug your ESP32 development board into your computer and follow these next instructions:
Go to Tools > Board, scroll down to the ESP32 section, and select the name of your ESP32 board. In my case, it's the DOIT ESP32 DEVKIT V1 board.
Go to Tools > Port and select a COM port available.
Press the upload button.
