2. Code example

We provide you with two sample codes to test your RGB LED. One code
which sets the LED to a color and then holds it each for 3 seconds (led.py)

and one code which sets the LED to a pulsating mode in dierent colors

(pwm.py).

The following example code is the one named led.py. First, you create a
file with the following command and copy the following code inside of it.

# Required modules are imported and set up

import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)

# Here you declare the output pin to which the LEDs are connected.

LED_ROT = 25
LED_GRUEN = 24
LED_BLAU = 23

GPIO.setup(LED_ROT, GPIO.OUT, initial= GPIO.LOW)
GPIO.setup(LED_GRUEN, GPIO.OUT, initial= GPIO.LOW)
GPIO.setup(LED_BLAU, GPIO.OUT, initial= GPIO.LOW)

print ("LED-Test [druecken Sie STRG+C, um den Test zu beenden]")

# Main program loop

try:

while True:
print("LED ROT 3 Sekunden an")
GPIO.output(LED_ROT,GPIO.HIGH) #LED red is switched on
GPIO.output(LED_GRUEN,GPIO.LOW) #LED green stays off
GPIO.output(LED_BLAU,GPIO.LOW) #LED blue stays off
time.sleep(3) # Lights up for 3 seconds
print("LED GRUEN 3 Sekunden an")
GPIO.output(LED_ROT,GPIO.LOW) #LED red stays off
GPIO.output(LED_GRUEN,GPIO.HIGH) #LED green is switched on
GPIO.output(LED_BLAU,GPIO.LOW) #LED blue stays off
time.sleep(3) # Lights up for 3 seconds
print("LED BLAU 3 Sekunden an")
GPIO.output(LED_ROT,GPIO.LOW) #LED red stays off

GPIO.output(LED_GRUEN,GPIO.LOW) #LED green stays off

GPIO.output(LED_BLAU,GPIO.HIGH) #LED blue is switched on
time.sleep(3) # Lights up for 3 seconds

# Clean up after the program has ended

except KeyboardInterrupt:

GPIO.cleanup()

sudo nano led.py

With the following command you can now run the program:

sudo python3 led.py

The second sample code is pwm.py. With the following command you can
create a file in which you can copy the following code.

# Required modules are imported and set up

import random, time
import RPi.GPIO as GPIO

GPIO.setmode(GPIO.BCM)

# Here you declare the output pin to which the LEDs are connected.

LED_Rot = 25
LED_Gruen = 24
LED_Blau = 23

# Set pins to output mode

GPIO.setup(LED_Rot, GPIO.OUT)
GPIO.setup(LED_Gruen, GPIO.OUT)
GPIO.setup(LED_Blau, GPIO.OUT)

Freq = 100 #Hz

# The respective colors are initialized.

ROT = GPIO.PWM(LED_Rot, Freq)

GRUEN = GPIO.PWM(LED_Gruen, Freq)

BLAU = GPIO.PWM(LED_Blau, Freq)
ROT.start(0)
GRUEN.start(0)
BLAU.start(0)

# This function generates the actual color
# Using the respective color variable the color intensity can be changed
# After the color has been set, the time is defined using "time.sleep",
# how long the color in question should be displayed

def LED_Farbe(Rot, Gruen,Blau, pause):

ROT.ChangeDutyCycle(Rot)
GRUEN.ChangeDutyCycle(Gruen)

BLAU.ChangeDutyCycle(Blau)

time.sleep(pause)

ROT.ChangeDutyCycle(0)
GRUEN.ChangeDutyCycle(0)

print ("LED-Test [druecken Sie STRG+C, um den Test zu beenden]")

sudo nano pwm.py

www.joy-it.net

Pascalstr. 8 47506 Neukirchen-Vluyn

# Main program loop:
# This has the task of creating a variable for each color

# and by with a For loop the color intensity of each color

# To go from 0-100
# By mixing the different brightness levels of the respective colors
# ethis creates a gradient

try:

while True:
for x in range(0,2):
for y in range(0,2):
for z in range(0,2):
print (x,y,z)
for i in range(0,101):
LED_Farbe((x*i),(y*i),(z*i),.02)

# Clean up after the program has ended

except KeyboardInterrupt:

GPIO.cleanup()

3. USAGE WITH THE ARDUINO

1. Connection

sudo python3 pwm.py

With the following command you can now run the program:

Arduino KY-016

GND GND

Pin 12 LED Blue

Pin 11 LED Green

Pin 10 LED Red

2. Code example

We provide you with two sample codes to test your RGB LED. To use
them, make sure that port and board are selected correctly in your

Arduino IDE.

The first code makes the RGB LED light up in red, green and blue 3
seconds each. To do this, copy the following code into your Arduino IDE.

int Led_Rot = 10;
int Led_Gruen = 11;
int Led_Blau = 12;

void setup ()

{
// Initialization of the output pins for the LEDs
pinMode (Led_Rot, OUTPUT);

pinMode (Led_Gruen, OUTPUT);

pinMode (Led_Blau, OUTPUT);
}

void loop () //Main program loop

{
digitalWrite (Led_Rot, HIGH); // LED red is switched on
digitalWrite (Led_Gruen, LOW); // LED green stays off
digitalWrite (Led_Blau, LOW); // LED blue stays off
delay (3000); // Waiting mode for 3 seconds

digitalWrite (Led_Rot, LOW); // LED red stays off
digitalWrite (Led_Gruen, HIGH); // LED green is switched on
digitalWrite (Led_Blau, LOW); // LED blue stays off

delay (3000);

// Wait mode for another three seconds in which the LEDs are then switched

digitalWrite (Led_Rot, LOW); // LED red stays off
digitalWrite (Led_Gruen, LOW); // LED green stays off
digitalWrite (Led_Blau, HIGH); // LED blue is switched on
delay (3000);

// Wait mode for another three seconds in which the LEDs are then switched

}

int Led_Rot = 10;
int Led_Gruen = 11;
int Led_Blau = 12;

int val;

void setup () {

// Initialization of the output pins for the LEDs
pinMode (Led_Rot, OUTPUT);
pinMode (Led_Gruen, OUTPUT);
pinMode (Led_Blau, OUTPUT);
}

void loop () {

// Within a For-loop the three LEDs are given different PWM values
// This creates a colour gradient in which the mixing of different
// Brightness levels of the two integrated LEDs so that different colours are created

for (val = 255; val> 0; val--)
{
analogWrite (Led_Blau, val);
analogWrite (Led_Gruen, 255-val);
analogWrite (Led_Rot, 128-val);
delay (1);
}

// In the second For loop, the gradient is passed backwards

for (val = 0; val <255; val++)
{
analogWrite (Led_Blau, val);
analogWrite (Led_Gruen, 255-val);
analogWrite (Led_Rot, 128-val);
delay (1);
}
}

You can execute both codes by clicking on the "Upload" button.

The second example code lets the RGB LED pulsate in dierent colors and
creates a gradient. Here, you copy again the following code into your

Arduino IDE.
