Brian shares his design for a simple sound-based memory game using a Picaxe microcontroller –

What it does
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.
