Sezme: a Memory Game for the Arduino

I have just started using the Arduino and I thought I would try my hand at a little project of my own.

Sezme is a game for the Arduino Uno that tests your memory. It is easy to build as I have only used LEDs, resistors, switches and a Piezo. In the game, the Arduino generates a series of random LED flashes. The player must then press the buttons and repeat the sequence of flashes in the correct order. If the player guesses incorrectly a buzzer sounds, the correct sequence is shown and the game starts again. If the player guesses correctly, a series of tones are played and the difficulty level goes up. There are 10 levels of difficulty. I can manage level 7. How far can you get?

• Arduino Uno
• 5mm LED: Red
• 5mm LED: Blue
• 5mm LED: Green
• 5mm LED: Yellow
• Resistor 220 Ohm * 4
• Resistor 10K Ohm * 4
• Tactile button * 4
• Piezo buzzer

Use the Fritzing diagram above to wire up the circuit.

The source code for the sketch is available for download from my GitHub repository.
