[vc_row][vc_column width=”1/1″][vc_column_text]On the wireless shield with RGB LED for Raspbery Pi, there is a RGB LED.

The python code used to control the LED is shown below:

import time
import RPi.GPIO as GPIO
GPIO.setwarnings(False)
GPIO.setmode(GPIO.BOARD)
GPIO.setup(15, GPIO.OUT)
GPIO.setup(16, GPIO.OUT)
GPIO.setup(18, GPIO.OUT)

RGB_R = GPIO.PWM(15, 50)  # channel=15 frequency=50Hz
RGB_G = GPIO.PWM(16, 50)  # channel=16 frequency=50Hz
RGB_B = GPIO.PWM(18, 50)  # channel=18 frequency=50Hz
RGB_R.start(0)
RGB_G.start(0)
RGB_B.start(0)
