Lightning is one of the great forces of nature. As you might expect, the huge power release will release detectable electromagnetic radiation.Team in [LVL1 Hackerspace] Assemble your own lightning detector; a method of recording the number of discharges In the atmosphere.
The device consists of a typical tank circuit tuned to 300kHz and a small telescopic antenna. A lightning strike in this area will cause an oscillation in the circuit, which is amplified and then detected by the Arduino. The Arduino measures the pulse voltage, which is proportional to the amplitude of the detected signal. Then turn on a circle of Neopixel LED according to the signal strength. In addition, when not actively detecting strikes, Arduino will use LEDs to display the current time and the binary count of the number of strikes detected since the operation.
This is a simple construction that can be a good introduction to the field of addressable LEDs and environmental monitoring. If you want to change it, you can also use SDR to detect lightning!
