Little Big Planet Sackboy faces with the Arduino Starter Kit

2015-02-18 Dan

Today, we’re going to build faces using LEDs and a joystick. Previously, we’ve wired up LEDs and learned how to control individual lights, how to draw pictures, and how to use a joystick. Today, we’re gonna put them all together to make a set of emotions based on the direction we push the joystick. Again, we’ve got the debounce, so the emotion will stay on our screen until we push the stick in a new direction.

Morse code is an ancient tongue spoken by the hooded figures who worship a terrifying obsidian pillar in the sunken city of – oh, wait. Sorry! Wrong blog.

We’ve briefly looked over producing Morse code and making music. What if we’re receiving Morse code now? Today, we’ll be teaching the Arduino to translate Morse code back into English and use a microphone at the same time.

Introduction to Speakers

Piezoelectric speaker

What you see in the picture above is a piezoelectric speaker – a tiny, electrically controlled diaphragm. On the back is a small crystal. When there is power flowing through the crystal, the size changes, bending the diaphragm. The change in the diaphragm is what causes sound and music as we know it. Today, let’s go through how we can make music with a piezo and Arduino.

Almost there now! What we have to do today is remove rows that are full so the game can be played and “won”. While we’re at it, we’ll add a game over sign. Previously, we got pieces to fall and collide with the rubble.

We’ve got control of our pieces. They move and they can rotate. Today we’re going to get them to fall and stop when they hit the bottom of our LED.
