We were introduced to the 555 timer chip. Two circuits were created out of it, one was the timer and the other was the modulation. We included photocells or light sensors to make sound react to light. When we tried this on the speaker we realized it was truly amazing how the speaker made sounds that would show us the movement of our hands, the sound changed also according to the position of the hand, not only the light. | |||
