#                      Pin.OUT Pin.IN
#  leds = Pin(15, Pin.OUT) this pin for output display or output reader
#  leds = Pin(15, Pin.IN)   input reader
#
#
#  if any(switch.value() for switch in switches): in multi list value checker
#
#  
 #                             Input
#  led.on()  / led.off()
#  led.value(1)  / led.value(0)
#  led.value() if enters value it will print the value if its on (1) or off (0)
#  
#  toggle() is used to change the states if on (1) turn into off (0)

#                               ADC
#  
#  adc=ADC(Pin(26))
#  adc.atten --> this for set th voltage 0 to 3.3v
#  adc.width  --> is used to set the o/p value in 16bit or 9bit or etc...
#  adc.read_u16 - This method reads the value from an analog pin using the ADC (Analog-to-Digital Converter) and returns it as a 16-bit unsigned integer (hence u16), which ranges from 0 to 65535.

#
#
#
#  Pull-Up Resistor (PULL_UP): Pulls the pin to a high state (1) by default, and it reads low (0) when connected to ground (e.g., by pressing a button).
#  Pull-Down Resistor (PULL_DOWN): Pulls the pin to a low state (0) by default, and it reads high (1) when connected to a higher voltage (e.g., by pressing a button).
