Making Lightning/Thunder effect for Diorama

Support
1

I am attempting to make a DIY Lightning Effect, video and diagram in the links below, for a Diorama.
Video: Lightning and Thunder Effect - Arduino, DfPlayer Mini, NeoPixels - YouTube
Diagram: Lightning and Thunder Effect - Arduino, DfPlayer Mini, NeoPixels - Random Making Encounters

However I am new and unsure what items are require, for example resistors, capacitors, LED lights and such. Any and all help iss appreciated, thanks.

Hi Jacobus,
Welcome to the forum :smiley:

I’ve had a quick look through that guide and grabbed a screenshot of the circuit used.

This all looks like a good beginner project to me and you should be able to source everything you need from our site.
I’d recommend starting with just the LED strip lights and getting that working, then tackle the addition of the MP3 player board later. We have a tutorial that covers getting NeoPixels (trade name for WS2812 LEDs) working with an Arduino you can find here:

The pin number in the code may need to change based on which Arduino board you use, but other than that the code should be pretty much ready to go.

Thank you, do you know what risistors are requiured? I have sorced most items .

Hi Jacobus,

There is a 470Ω resistor on the input data line of the NeoPixel. There is also a voltage divider made up of a 1kΩ and 680Ω resistor. The ratio of the values in the voltage divider is the most important part as that determines what voltage it outputs.
If you want to get your head around NeoPixels(WS2812) LEDs then Adafruits uberguide is fantastic!

Hi Jacobus,

If you’re after a really convienient resistor kit I would go for one of the following:

These will last you quite a few projects and include all of the common values at 1/4 W, not high power but lets you experiment with MCU’s.

Liam.
