To figure out what I want to do as my final project, I surfed the internet to come to know what kind of circuits I can built. After searching for the possibility to make LEDs blink in different rhythms, I found a way to let an LED blink following the rhythm of music. | To figure out what I want to do as my final project, I surfed the internet to come to know what kind of circuits I can built.

*The length of the LED flash depends on the capacity of the capacitor (e.g. 2.2 mF ≈ 1 s). The higher the capacity, the longer the LED blinks. | *The length of the LED flash depends on the capacity of the capacitor (e.g. 2.2 mF ≈ 1 s). The higher the capacity, the longer the LED blinks. | ||
