Solving puzzle in Rhem3 with sound sensor
Rhem3 is a puzzle game for pc. One of the puzzles is matching a sequence of tones. The matching is based on the duration of each tone. My old ears were having a hard time making the fine distinction that was needed. NXT and the sound sensor to the rescue! A 20 line program was all it took. It waits for an initial sound to trigger it and then graphs the volume and duration on the display. Each pixel along the horizontal axis was 30 milliseconds (3 seconds total). Armed with these graphs it was easy to make the matches and solve the puzzle. There were 8 sequences of 3 tones each. Sad to say, before using the NXT, I didn't have a single one correct.
This might represent the most practical use I've ever had for my NXT.
My son considered it cheating, but I considered it clever (in my humble opinion).
