We can pick these fluctuations using Arduino’s analog pins.As you might already know, the pins on the Arduino board allow for voltages between 0v and 5v, anything below 0v and above 5v will not be read, hence data will be lost. The arduino stops animating the little cloud and asks the sensor what it wants. Kinda of a cool little gadget to have in your pocket next time it thunders!
More importantly, voltages below 0v will potentially damage the pin. Or maybe there is some interference between antenna and I2C as both are working on the very similar frequency (we see at the code 400kHz as a I2C speed).
Most lightning detectors often cost too much for the normal hobbyist, however this does not mean one cannot enjoy lightning detection and the physics behind it.

When using an Arduino Ethernet I chose to use pin 9 for SPI Chip Select since 10 is used by the Ethernet chip, and pin 2 was used for interrupts since this is int.0 on the board. I also decided to just hardwire all the parts together so it would be stable when carried around in it's soon to be designed box.
The Thunder Board - DIY IOT lighting detector and lightning simulator. Or you could do that!
That is, 28,000 samples per second.The Arduino analog pins can only give us 9,600 samples per seconds.
The Lightning sensor has the capability to utilize SPI or I2C. Reference the pseudo Schematic I included if you need help.UPDATE: I found and corrected a small bug that Would cause the detector to freeze when it detected a unknown signal. Most Arduino lightning detection projects basically just tell you that something "lightning-like" occurred.
Hi, in code there is #define SI_PIN 9. if we look at the wiring diagram the pin 9 is not plugged?
I kept 104 as at original code but I saw at other codes 74. It has everything you'll need to build this the same way I have.The Nokia 5110 libraries are available in the Arduino IDE libraries manager. The lightning detector can tell you the distance to the front of the storm 40 km away with an accuracy of 1km.

Or if you prefer. This would allow more data onscreen at one time and opened up the possibility of a little "monitoring activity" animation. In this tutorial, using a surprisingly simple circuit we will be able to detect lightnings from around 10-20 km away, which is to say the least impressive.
Kinda of a cool little gadget to have in your pocket next time it thunders! In my searching I found the AS3935 Lightning detection sensor. Recent research shows that a rare lightning event may be preceded by Gamma ray bursts, called Dark Lightning, extending the EM spectrum even further. I immediately wanted to try one out!
Free access to maps of former thunderstorms. 11 months ago SwitchDoc Labs is raising funds for The Thunder Board - IOT Lightning Detection for Makers! Our little Arduino will have an antenna (sort of), a piece of wire that will pick fluctuations in electromagnetic spectrum specifically around the 7-9kHz. How would I do this without the pushbuttons? In series with the 3.3M Ohm resistor attach a wire to pin A4 (blue wire), this will give us exactly 2.5v on pin A4. My 3D print work is ready so I'm testing the software now.
All the connections are direct and there's no need for electrical component parts like resistors, capacitors or transistors. <> The possibilities are endless!Back to the case... basicly it's a box. As mentioned above, the frequency we need to pick up from the lightnings, is around 7kHz and to read a semi-decent wave the sample rate has to be 4x as much, giving us 4 readings per wavelength. The button panel however... that was a different story! Mar 05, 2010, 07:16 am. Thankshy i build this this but i get very often a chrasch only reset bring him back to work what was the update and is it really online in the zip fileHello, any alternate display available or suggested? The project i am proposing is essentially made of three elements: lightning detector, available on the breakup board, an Arduino Uno board, which duty is to analyze the signal provided by the sensor, process it and show on serial LCD display (which is the third element of the circuit) the information extracted, i.e.
just a box with holes for the buttons and the display. Then attach a wire which will act as an antenna (green wire) of around 6-8 inch in length. stream
Reply The arduino then updates the display to show what it's learned.
