Page 5: Introduction
RGB LED). This means that RGB LED can produce light in three different colors. There are NO on-board resistors in series with LED pins. When the KY-009 module is connected with the Atmega328p or Raspberry Pi, an external resistor for every color pin has to be connected in series with the pin (as shown on the connection diagrams later in the eBook). -
Page 6: Specifications
Dimensions: 19 x 15mm [0.73 x 0.6in] The pinout The KY-009 SMD LED module has four pins. The pinout diagram is shown on the following image: Note: Use resistors for color pins, or you can demage the module. - 4 -... -
Page 7: How To Set-Up Arduino Ide
How to set-up Arduino IDE If the Arduino IDE is not installed, follow the link and download the installation file for the operating system of choice. For Windows users, double click on the downloaded .exe file and follow the instructions in the installation window. - 5 -... - Page 8 For Linux users, download a file with the extension .tar.xz, which has to be extracted. When it is extracted, go to the extracted directory and open the terminal in that directory. Two .sh scripts have to be executed, the first called arduino-linux-setup.sh and the second called install.sh.
- Page 9 Almost all operating systems come with a text editor preinstalled (for example, Windows comes with Notepad, Linux Ubuntu comes with Gedit, Linux Raspbian comes with Leafpad, etc.). All of these text editors are perfectly fine for the purpose of the eBook. Next thing is to check if your PC can detect an Atmega328p board.
- Page 10 If the Arduino IDE is used on Windows, port names are as follows: For Linux users, for example port name is /dev/ttyUSBx, where x represents integer number between 0 and 9. - 8 -...

Page 11: How To Set-Up The Raspberry Pi And The Python
How to set-up the Raspberry Pi and Python For the Raspberry Pi, first the operating system has to be installed, then everything has to be set-up so that it can be used in the Headless mode. The Headless mode enables remote connection to the Raspberry Pi, without the need for a PC screen Monitor, mouse or keyboard. -

Page 15: Python Script
Python script import RPi.GPIO GPIO from time import sleep GPIO.setmode(GPIO.BCM) GPIO.setwarnings(False) Blue_PIN Red_PIN Green_PIN GPIO.setup(Red_PIN, GPIO.OUT, initial=GPIO.LOW) GPIO.setup(Green_PIN, GPIO.OUT, initial=GPIO.LOW) GPIO.setup(Blue_PIN, GPIO.OUT, initial=GPIO.LOW) red = GPIO.PWM(Red_PIN, 100) # PWM, frequency 100Hz green = GPIO.PWM(Green_PIN, 100) # PWM, frequency 100Hz blue = GPIO.PWM(Blue_PIN, 100) # PWM, frequency 100Hz red.start(1) green.start(1) - Page 16 Save the script by the name SMDRGBLED.py. To run the script open terminal in the directory where the script is saved and run the following command: python3 SMDRGBLED.py and watch the color changing magic. When starting the PWM, with the following line of code: red.start(1) use any number different than 0, because if the number 0 is used, that disables PWM on the selected GPIO pin.
