How To Make A Sound Controlled Light Module

#DIY IS FUN

Hello there fellow Steemians and welcome to my quick tutorial on how to put together a DIY kit I purchased from Banggood that they call a Voice Controlled Melody Light. I enjoy these little DIY kits and have put several together in my time. I find them good soldering practice and I'm relatively new to electronics so I find these kits handy, fun and pleasing.LED lights reacting to the sound of the snapping fingers

Step 1: Sort the parts

Every good build begins with organization. I lay out my components so that I can easily grab the part I want as well as confirming I have the correct number of parts.

  • 5 LED's
  • 1 Microphone
  • 1 1μF Electrolytic Capacitor
  • 1 22μF Electrolytic Capacitor
  • 1 4.7k Resistor
  • 1 10k Resistor
  • 1 1M Resistor
  • 2 9014 Transistors
  • 1 2-pin connector
  • 1 PCB
    Speaking of the PCB, here's a close up of the top and bottom for you just incase you want to save a few dollars and reverse engineer this!

While I'm not colorblind, I do find reading resistor values to be a royal pain. So I purchased this handy component tester which tells you the value of your resistors as well as many other components. You can also do this with a multimeter. But I find this quick and easy.

Soldering time

Well, since we got those resistors sorted out we might as well start by putting them into the PCB. It's best to tackle the components from smallest to large when the design allows it.

Bend those legs out

Solder them into place

And snip those leads off.

Next up are the two transistors

Be careful soldering these together with the holes being so close together.

Electrolytic capacitors. Mind the polarity. The long lead is positive. The short leg also has a white stripe, which is negative.

Time to slap that microphone in place. By virtue of the design of this PCB and microphone combo, it can only be put into place in the proper direction. If you are reverse engineering this make sure to figure out the polarity of the microphone.

Remember when I said go smallest component to largest? Well, I forgot. And this guy is a bit tricky to hold in place when you're soldering it, but I managed.

Woo, home stretch! Just 5 LED's to go! Remember that LED's have a polarity and the long leg is the anode or positive lead

And finally, apply 5V to the +,- pins

Here is a very short video of the completed module in action. It's quite simple in its design yet rather amusing to mess around with by playing various songs or seeing if the snoring from your pet dog can make it light up.

Thank you for taking the time to read this blog. If you found this trying to find a tutorial on how to put together this Diy Voice Controlled Melody Module, congratulations on completing it.

A piece of very useful and vital information on how to make a sound controlled light module. Very impressive buddy!

As a matter of interest, @build-it and @neoxian-city has collaborated to reward steemians with over 200 liquid STEEM and a couple thousand of their tribes tokens in an ongoing, do check it out and considering participating :

I have SO MANY GAMES TO PATCH! I can't wait to fly south in the summer and update all my favorite games and get online for a few sessions to scratch this itch. Luckily I have all these fun diy kits to pass my time and a 3d printer!

I was thinking maybe this is a blog for tag DIY instead of howto, i dont think that one excited untill you used it. And you might want to see steegsten as a tag maybe it can belong there aswell

Ah, I didn't know I "created" a tag for steemit hehe, that's kinda cool but I'll definitely make sure to swap those tags in the next post. Thanks for the tip!

It does look like an interesting project. I constantly wonder if I should start on learning to do these kind of electronic projects. Then somehow I get blocked on what will I do with all these things.
Does your project ends here? Or do you manage to use this Voice Controlled Melody Light in something else? Does it get stored for spare parts for a later project? What is the afterlife of these small projects?

There is definitely passion in building this controller and the result is amazing. The demonstration in the video of the operation of the light contractor with sound is almost magical.
You have taught me a lot today. I am NOT going to build something similar like what you did because I don't even have the basic knowledge but I learned that plates like these should be the ones used in the water fountains at night. There the lights are colored and I imagine that they also contract it.
A big hello @lacking

hi dear @lacking, great post !! very funny, although I don't think I'll ever do one;)) in the end it turns on if the dog snores ?? !! congratulations on your work and on your curie vote

Yea, I have to slide it fairly close to her, but it will light up and flash along with her snoring. We've woken her up several times giggling about it

I liked this information, you make it look like something anyone can do, I don't know about electronic and yet I understood the tutorial.
Congratulations, you have been deleted for a Curie vote, which brings a lot of traffic to your blog!
