Homework 2

Simple elevator system with three floors, scalable to any number of floors.
The elevator has a button and led for each floor.
It doesn't stack the requests, it goes to the first requested floor and after it finishes it goes to the next one.

Components used:

• Arduino Uno
• Breadboard
• Buzzer
• 3x Push Button
• 4x LED
• 5x 220 OHM Resistor
• wires

Homework 3

Code enables a "cursor" to move around a seven segment display with a joystick and toggle the segments with it's button.
Highlighted segment is blinking whether it is active or not.
If you hold the joystick button, all the segments will be reset.

Components used:

• Arduino Uno
• Breadboard
• 8x 220 OHM Resistor
• 7 Segment Display
• Joystick
• wires

Homework 6

Bomberman game on a 8x8 LED Matrix.
Very simplified version, you have to break all the blocks to win.
The control is done through a joystick, clicking it will place a bomb.
The player can move around and place bombs.
The bombs explode after a certain amount of time and destroy the blocks / walls around them.
You die by touching the explosion.

Components used:

• Arduino Uno
• Breadboard
• 8x8 LED Matrix
• Joystick
• MAX7219 Driver
• 10k Ohm Resistor
• C104 Capacitor
• C4 10μF Capacitor
• wires

Using a joystick, you can navigate through the menu and select the desired option.
The menu is displayed on a 2x16 LCD Display.
Also added dots left on the screen while playing.

Components used:

• Arduino Uno
• Breadboard
• 8x8 LED Matrix
• Joystick
• MAX7219 Driver
• 10k Ohm Resistor
• C104 Capacitor
• C4 10μF Capacitor
