Codey Rocky - Functions F1: Hello World!

Description

In this lesson, students will create a function that has Codey Rocky say "hello" every time it is called.

Objectives

• students will be able to describe what a function is

• students will be able to program a function using Codey Rocky

Preparation

• Review our introductory video to get accustomed to Codey Rocky's different features: https://www.youtube.com/watch?v=q7t-H7s7yYM&t=13s

• Fully charge the tablets and robots.

• Install mBlock 5 on a compatible Windows or Apple device: https://www.mblock.cc/en/download/

Introduce Functions

Introduce Functions by once again relating it to a real life activity.

Say "Functions are a group of instructions that you can use over and over again. For example.

Function Name: Wash Hair

Get hair wet

Put Shampoo in hair

Lather shampoo to wash

Rinse hair

This function can be used over and over again. In programming, functions are used where there is something that is repeated often so that it doesn't have the be written out every time. In this lesson we will practice writing our own functions."

Connecting to mBlock 5

Introduction to mBlock 5

Project your computer screen and open the mBlock 5 program. Point out the icon and how it can be found in your specific system or device. Discuss the wireless dongle and how it is used to connect a specific Codey Rocky to a computer. The dongle is required for the Codey Rocky to be connected to the computer, so keeping that dongle safe and with the proper Codey Rocky is very important.

(Optional) Work with the class to label their dongle and device if they are not labelled already. These can be permanent device identifiers using a label maker (i.e Codey Rocky 1) or have the class temporarily name their Codey Rocky and label it with a sticky note or piece of paper and tape. (even if a device has a permanent label, it is always fun to allow students to name their devices)

Model connecting Codey Rocky to mBlock 5 by performing the following steps:

• Turn on Codey Rocky

• Open mBlock 5 if it is not open already

• In the area where it says "Connect your Device" click the BLUE connect button.

• Plug in the USB dongle.

• Select the USB dongle from the drop down. It will be listed as "/dev/tty.wchusbserial14xx" with the last two number being different depending on the port the USB is plugged in to (ex. 1410, 1420)

• You will know the device is connected when the window in mBlock 5 changes, indicating a proper connection and your ability to now upload code to Codey Rocky.

(Optional) Have students connect and disconnect their Codey Rocky from mBlock 5 a number of times to practice the process so they can do it independently going forward when instructed.

Demonstrate Hello World!

Build and upload the following code to Codey Rocky. This code creates a function making Codey Rocky say "hello" every time it starts up. The Function is defined with the set of blocks on the left, while it is called out in an Event on the right.

Hello World!

Keep the code created to demonstrate this lesson on your screen.

Say "Now that we have learned how to make a function, lets see if you can make a few more and use them in a sequence to have Codey Rocky say other things and changes the face it makes at the same time."

Walk around the room assisting as needed. Ensure that students are using Functions to code Codey Rocky's actions as opposed to just putting new actions and expressions in sequence.

Wrap Up

Say "Now that we've used a function to be able to repeat instructions anytime we want, we are going to revisit our Dance Party! lesson from before and add functions to it so we can mix up Codey Rockey's dance moves so we all have different moves at different times! Are you ready for a Dance Party?!"
