Musical Tone Memory Game Known as Sing-Along

The project is based on the ATtiny12 microcontroller designed for one to three players wherein a random sequence of notes is played and the player(s) listens while singing/humming to mimic the sequence.

The popular 80’s game Simon plays this tradition Sing-Along musical tone memory game. During the game, a “lose” sound will play if the player sings in an incorrect note or does not sing a note within the allotted time. A “win” sound will play automatically if the entire 16-note sequence is correctly sung by the player. To indicate which player’s turn is in progress, several LEDs are included in the game which are also used for following the notes as they are sung or played.

The input from an electret microphone is being processed by an analog comparator fed by an analog front end and the inputs over a wide range of sound levels is detected by the MCU because of the automatic gain control loop. Several pins of the MCY are used for multiple functions so there are only 5 I/O pins available. A 9V battery is used to power the system and is fed through a transistor.
