STEP 1

Ask

How do remote controls work?

How do car wheels move when the car is driving in different directions?

How would you make a remote control from your computer keypad to control Phiro's wheels to move?

STEP 2

Imagine

Imagine what you would need in Snap and Phiro to solve this challenge.

Create conditions to connect Arrow Key to Phiro Direction. Example, If Up arrow is pressed, Phiro moves Forward.

How many steps would it take to change Phiro's directions? How would you imagine decreasing the number of steps to make the process more efficient?

2 ways to do this:

1. Long Code

2. Short Code

STEP 3

Plan

Explore how Phiro's motors turn when moving forward, backward, turn right & left. Plan the conditions to incorporate the computer's key arrows to each of Phiro's movements.

STEP 4

Create

Create Phiro's remote control program

1. Make a Block

2. Define the Block

3. Create remote control

Up = Forward
Down = Backward
Left = Turn Left
Right = Turn Right

Define the block with the given Input value speed - variable 'L' denotes speed.

Remote Control program

STEP 5

Remix

Remix your remote control to use Phiro's LEDs to flash different color lights for different directions!

STEP 6

Share your very own Phiro Remote Control creation using #MyPhiro and we will share it with the world!
