Blink

The LED Blink application is a project that allows the user to control the blinking of an LED using an SMD and an RGB LED Module. This project is designed for simplicity, making it an ideal starting point for those wishing to experience the SMD hardware control using the SMD libraries.

"Blink" Project

Project Key Components

1. SMD

   The SMD acts as a bridge between the script and the RGB LED Module. It is responsible for interpreting the commands sent by the script and translating them into actions that toggle the RGB module.

2. RGB LED Module

   The RGB LED Module is designed to emit different colors, allowing users to experiment with different lighting effects.

3. SMD Libraries

   The SMD library is at the heart of the application. It communicates with the SMD using a specific communication protocol, sending commands to turn the RGB LED on or off, adjust the color, or set a specific blinking pattern.

Project Key Features

• Detailed Control over the LED

  The user can easily control the LED of the RGB LED Module colors by simply using the necessary function of SMD libraries. The LED on the module can emit all RGB color values.

Project Wiring Diagram

Getting Started

1. Hardware Setup

   • Connect the SMD to the PC or Arduino board using USB Gateway Module or Arduino Gateway Module.

   • Connect the RGB LED Module to the SMD using an RJ-45 cable.

   • Make sure that the SMD is powered and all connections are correct.

2. Run the Script

   • Run the script on your computer. This will establish communication with the SMD and initiate control of the RGB LED Module.

3. Experience and Customize:

   • Explore different blinking patterns, change the color of the RGB LED to suit your preferences.

Project Codes

Python Code

from smd.red import *

SerialPort = "COM3"     # Serial port of the USB gateway module
baudrate = 115200       # Baud rate of communication
ID = 0                  # ID of the SMD
rgb_module_id = 1       # ID of the RGB LED module

master = Master(SerialPort, baudrate)       # Defines the USB gateway module
master.attach(Red(ID))                      # Gives acces to the SMD of specified ID
master.scan_modules(ID)                     # Scans and identifies the modules that are connected to the SMD

while True:
    master.set_rgb(ID, rgb_module_id, 255, 0, 0)        # Numbers are correspond to the R - G - B color values
    time.sleep(0.5)                                     # Value can be changed to see how the blinking frequency changes
    master.set_rgb(ID, rgb_module_id, 0, 0, 0)          # Sets all colors to zero, meaning turning the RGB LED off
    time.sleep(0.5)                                     # Value can be changed to see how the blinking frequency changes

Arduino Code

int rgb_module_id = 1;              // ID of the RGB LED module
void setup() {
    master.begin();                 // Starts the communication
    master.scanModules();           // Scans for the connected modules
}

void loop() {
    master.setRGB(rgb_module_id, 255, 0, 0);    // Numbers are correspond to the R - G - B color values
    delay(500);                                 // Value can be changed to see how the blinking frequency changes
    master.setRGB(rgb_module_id, 0, 0, 0);      // Sets all colors to zero, meaning turning the RGB LED off
    delay(500);                                 // Value can be changed to see how the blinking frequency changes
