+Lets write some more code in Thonny
+\\
+\\
+{{ :lef-flash.png?650 |}}
+\\
+Here is the full Micro Python code that we are using.
+\\
+<code:python | download>
+# Import the picozero LED class
+from picozero import pico_led
+# Import the time module for delays
+from time import sleep
+# Create an LED object for the onboard LED
+led = pico_led
+# Run forever
+while True:
+    # Turn the LED on
+    led.on()
+    # Wait for 0.25 second
+    sleep(0.25)
+    # Turn the LED off
+    led.off()
+    # Wait for 0.25 second
+    sleep(0.25)
+</code>
+In this code we are using a **Loop**. The While True: runs forever, and loops around the four lines of code. The comments should make this Micro Python code very easy to understand.
+\\
+\\
+Here we can see there is an on time of 0.25 seconds and an off time of 0.25 seconds, so each on/off cycle is 0.5 seconds so every second the LED goes on and off twice.

+\\
+We will explore a simpler way to achieve a flashing LED in another example.
