Dear Sir Charles,
Thank you for reading my post. Maybe the idea i described above is
not so clear. After I read your reply, I think I should use the term
"SOUND LEVEL instead of music frequency", so here is what I want in
the circuit, the microphone built in the circuit everytime it receives
the sound, depending on the sound level, different color LEDs are
changed accordingly to the sound level.
As you said If I decide how I want my lighting to respond, this is
what I want; let say LEDs have different color from blue, green,
yellow, purple and red, then the color of LEDs will change in order
from blue, green, yellow, purple, and red which are depending on the
Can you help me with the circuit?
