Fix the code · difficulty 2 of 3
You rigged a little hum box in your hideout so the quiet stops feeling so big — a steady 330 Hz drone off a piezo buzzer. Loaded the code, and nothing. The buzzer's wired fine, so the code's got a bug in it. Track it down and get your hum back before the silence wins.
