*The NodeMCU ESP8266 board has 30 pins connected to the development board.
*Out of the 30 pins, 17 are GPIO pins.
*These GPIO pins can be used as:
ADC Channel: 10-bit ADC (Analog to Digital Converter) channel
UART interface: used to load code serially
PWM outputs: for dimming LEDs or controlling motors
SPI and I2C interface: to hook up all sorts of sensors and peripherals
I2S: to add sound to your project
*These GPIO pins are multiplexed, meaning a single GPIO pin can act as PWM/UART/SPI.
