Adding Sleep
- Project: Traffic Lights
- Lesson 2/3
Introduction
It’s time to add a little automation to our traffic light! The Little Python is a computer. As such, it reads through code and executes them REALLY quickly! As such, it is oftentimes essential to let it wait a bit before executing its next line of code. As such, we’ll be learning about “sleep” and why it is as essential for computers as it is for human beings!
Components Needed
- Little Python Brain
- A tablet/phone/laptop
1
Importing the Sleep Function
2
Using the Sleep Block
From the Operators category, simply drag the sleep(1) block to the end of our last block! This lets the Little Python wait for a bit – 1 second, in this case! – before executing the next line of code.
3
Adding the Next Colors in the Sequence
Now that our libraries are ready, it’s time to set up the NeoPixel! The Pin(12) denotes the pin that our NeoPixel is connected to while the 1 represents the number of “pixels” that we have. Let’s leave it as is for now!
