Thunderstorm With Colored Lightning

Thunderstorm With Colored Lightning

What’s In This Page

This page shows you how to make a thunderstorm that flashes various displays of blue and/or white lightning strikes. It takes you through how the ThunderBoard Pro kit is assembled.  It then describes the many different light strike routines from which you can choose. Finally from this page you can download – free- any or all such programs.

If you are using a phone, at the bottom of the page there are links to many  supplies for modelers. Otherwise those links are in the sidebar to the right. You can also find other information  by using the search function that is in the navigation bar above.

About The Assembled Circuit Board

With time we have been developing more advanced thunder boards.  Each advanced board has additional capabilities.  Regardless of the board that you have, the assembly process is essentially the same. Only the look of the board and what it will do will vary.

Features

  • Controls WS2812B LED strips.
  • Arduino mini Pro controls flashes on LEDs strips.
  • Arduino mini Pro comes fully programmed.
  • Programs on the Arduino Mini Pro can be changed.
  • Thunder sounds played are on an SD card in the mini MP3 player.
  • Can play sounds on an external Bluetooth speaker.
  • Can provide gate voltage to MOSFET switch to activate external application.
  • Speakers can play monaural or stereo.
  • Can connect to 5 V amplifier for more impressive thunder in effect.

Connections

Screw connectors on boards will have the following labels.

Screw Connectors Labeled – +5v E1 E2. – A 5v power supply connects to – and +5v.  E1 and E2 output +5v whenever the MP3 is powered up.  These outputs can be used to activate programs housed on remote boards. One such board could use another mp3 player to broadcast rain sounds. So you not only have thunder and lightning but also a background rain storm. How that is done at MP3Remote.

Screw Connectors Labeled +5v Audio L Audio R – . These are used when you broadcast your thunder on a remote Bluetooth speaker.  How that is done is at Bluetooth Speaker.

Screw Connectors Labeled S1 – – S2. – You can connect two speakers at these points. Such connections will give you stereo output. It here that you can attach a 5v amplifier.  How that is done is at 5v Amplifier

Screw Connectors Labeled Data(Number 1 to 3) – +. WSb2812B LED strips are conned here. It is possible to connect 3 strips. In this case we will connect only one strip and that shall be to DATA!.

Mini MP3 Player. – The player is simply inserted, oriented as directed on the board, into the DuPont pin sockets. It comes to you with and SDcard on which are some standard thunderstorm sounds. You can change them,  How to do that is here.

Arduino Mini Pro – This Arduino board is set up to control one LED strip and that is the one on DATA1. It comes to you with a storm program loaded. You can change that program.  How to do that is at FTDI Programmer. A list of the programs available is below.

The Materials

The project is assembled from a kit that contains a circuit board and the necessary elements to be added to the circuit board.  You can get that kit here.

The parts are shown in the image to the left.

The Arduino board comes fully programmed with the most popular thunder and lightning display.. There are other programs that will you different displays.

Assembly Notes

The screw terminals come as 2 pin units.  They are designed to be joined by using the slots on each side. So, for example to make a 4 pin screw terminal, join two two pin terminals.

The pins on the MP3 Player and Arduino board  connect to the circuit board via DuPont pin sockets. Cut the pin sockets to length and insert the pins into the sockets.

The sockets will be soldered to the circuit board. With the pins or the MP3Player and and Arduino board inserted, you can be sure that the pin sockets will be vertical when soldered to the board.

Note the text on the board that shows where you place the circuit elements.

All connections between parts are made via traces on the circuit board.

The circuit board shows exactly where the elements are placed on the board,

So it is a simple matter of inserting the parts, soldering them in place with a fine point soldering tip on which there is a minuscule drop of solder and finally trimming off any protruding wires or pins to a comfortable length.

Now add all the elements to the board and solder in place.

 

ThunderboardThe board ready to use.

The SD card is loaded with the recommended sounds for this project. If you wish to use different thunder sounds, this page shows how to load them on the card .  You can get other sounds here. Player Sounds

The flash rate depends on the thunder sounds that you have on your SD card.

How To Use

The program controlling the LED strip can be used with strip laid out in a line or coiled inside a puff ball cloud. You can add a second strip to the same screw terminals and make either a second cloud or a larger single cloud. To read about information about doing both, Click Here

The storm starts when the board is powered.  You can switch it on and off with a manual switch, push button, an ESP32 switch  or a phone using an app such as Serial Bluetooth Terminal.
