How to write code for alternate Blinking LEDs with different colors in Arduino Alvik?

Join Online/Offline short term course to learn advanced programming of Arduino Alvik at Vidyasagar Academy. Register now at this link.

If you are already familiar with Arduino Alvik environment, then you can proceed with the following post. However, if you are new to Arduino Alvik, then we suggest you to read this post on Arduino Alvik basics first!

As we know there are two on board multicolor LEDs on top of the Arduino Alvik. Let us see the following code to blink these LEDs alternately by changing their color.

The following code is freely available for logged in users.

from arduino_alvik import ArduinoAlvik
from time import sleep_ms

# Initialize the Alvik robot
alvik = ArduinoAlvik()
alvik.begin()

# Make the two LEDs off initially
alvik.left_led.set_color(0, 0, 0)
alvik.right_led.set_color(0, 0, 0)

while (True):
  # Blink the two LEDs in Red for 5 times
  for _ in range(5):
      alvik.left_led.set_color(1, 0, 0)  # Turn on LEDs (Red)
      alvik.right_led.set_color(1, 0, 0)
      sleep_ms(500)  # Wait for 500 ms
      alvik.left_led.set_color(0, 0, 0)  # Turn off LEDs
      alvik.right_led.set_color(0, 0, 0)
      sleep_ms(500)  # Wait for 500 ms
  sleep_ms(1000)
  
  # Blink the two LEDs in Green for 5 times
  for _ in range(5):
      alvik.left_led.set_color(0, 1, 0)  # Turn on LEDs (Red)
      alvik.right_led.set_color(0, 1, 0)
      sleep_ms(500)  # Wait for 500 ms
      alvik.left_led.set_color(0, 0, 0)  # Turn off LEDs
      alvik.right_led.set_color(0, 0, 0)
      sleep_ms(500)  # Wait for 500 ms
  sleep_ms(1000)
  
  # Blink the two LEDs in Blue for 5 times
  for _ in range(5):
      alvik.left_led.set_color(0, 0, 1)  # Turn on LEDs (Red)
      alvik.right_led.set_color(0, 0, 1)
      sleep_ms(500)  # Wait for 500 ms
      alvik.left_led.set_color(0, 0, 0)  # Turn off LEDs
      alvik.right_led.set_color(0, 0, 0)
      sleep_ms(500)  # Wait for 500 ms
  sleep_ms(1000)
