• 1 x Tinkercademy breakout board
• 2 x ADKeypad

Defining variables and start screen

(a) bottom_position_of_A and bottom_position_of_B refers to the Y-coordinate of the position of the bottom half of the 2 pong boards.

(b) ball_horizontal and ball_vertical refers to the direction of which the ball goes.

Functions for moving of the pong boards
We can't have our pong boards moving off-screen, so we have set a boundary for the movements of the pong board.

Functions for the movement of the pong ball
(a) ball_bounce() refers to the ball bouncing off the pong boards.
(b) ball_bounce_top_bottom() refers to the ball bouncing off the top and bottom boundaries of the screen.
(c) ball_move() refers to the ball moving in the direction dictated by ball_vertical and ball_horizontal.

Now, we will combine all ball movements into one big function. This function will be called main_game.

Define game over
This function shows a string "A loses!" or "B loses!" depending on which player lost, and then resets the game.

Combine main_game and game_over together to form the game itself. Pong board movements are also mapped to their respective buttons on the ADKeyboards.

After all that, download the code into your micro:bit and it's done. Find a friend to play the pong game with you!
