Karel the LED can’t turn right, but he can make some great LED art!
The goal of this activity is to download the JavaScript code given below onto a board, then USE the program to introduce new students to the micro:bit. Students will not do the coding this time. They will be users to get familiar with the board.
How to play
A button Turn Left
Does not draw anything just changes the direction Karel (the flashing led) is facing
B button Move Forward
Moves Karel forward one step and leaves the LED on behind him
shake Jump
Moves Karel forward one step without leaving the LED on behind him
A+B button Hide Karel
Shows or hides Karel (the flashing LED), to be used once your artwork is complete
Reset button Clear the board and restart
Restart the program and clear the board
Note, that there is no way to erase, other than restarting.
See if you can make each pattern below using A, B, and shake. Once you have completed a challenge press A and B at the same time to hide Karel. For patterns that you design decide which LEDs you want to turn on and then make that design with Karel.
