My Code:
import serial # add Serial library for Serial communication
Arduino_Serial = serial.Serial('com4',9600) #Create Serial port object called arduinoSerialData
print Arduino_Serial.readline() #read the serial data and print it as line
print ("Enter 1 to ON LED and 0 to OFF LED")
while 1: #infinite loop
input_data = raw_input() #waits until user enters data
print "you entered", input_data #prints the data for confirmation
if (input_data == '1'): #if the entered data is 1
Arduino_Serial.write('1') #send 1 to arduino
print ("LED ON")
if (input_data == '0'): #if the entered data is 0
Arduino_Serial.write('0') #send 0 to arduino
print ("LED OFF")
have no idea why
