A duck. A cat. A rooster. Your mom.
Quick, remember those four items and hold that thought. You’re going to need a sharp memory for building and playing this sweet memory game that you can build yourself, sans Arduino. It uses a Picaxe microcontroller, ensuring a headache of assembly-based program for all involved. The outcome does sound pretty rewarding though:
MemSounds is a sound based memory game played in rounds. In the first round it plays one of 4 different sounds at random. Each sound represents a different switch in the device. After the sound is played you get a turn to copy the original sound by pressing a switch. If you get the sound right, MemSounds will play two sounds in the next round and so on. The limit is about 100 rounds.
