Hi there!
New here, wondering about some stuff for fun projects at home (my electronics classes go back 18 years ago, please forgive me if I am not very proficient).
A friend of mine made a home-project: playing a sound on his computer, and a microphone detects the sound, and generates a current to light up a LED (he made a "lightning cloud", with blue light inside a white fluffy thingy while the computer is playing thunder sounds).
I suggested him to light the "sky" just a bit when there is no thunder, instead of being either all black/dark/night or all lit up. He loved the idea, but he thought he had to use an arduino.
Question: is it possible to extend his current project so that the LEDs emit a dim light when there is no thunder? I thought of maybe using an OR gate (with two input: the basic resistor allowing a dim light, and the microphone allowing a bright light if sound)? Or maybe something like a "digital potentiometer" commanded by the signal sent by the microphone?
Do you reckon he can do this without an arduino, to keep it as simple as possible?
Sorry if I am noob, I have not touched electronics for ages...
Thank you all
