Sensitive Arduino Lightning detector with homemade sensor

A lightning detector is a device that detects lightning produced by thunderstorms. In one of my previous videos, I showed you how to make such a detector with the help of the AS3935 sensor board which is specially designed for this purpose. This time I will show you how to make same such device, but now with a homemade detector circuit based on cheap AM Receiver IC TA7642. This design is many times cheaper, its sensitivity is much higher, and Also the resistance to local disturbances as various sparks from electrical devices is very high. The ingenious idea of using AM receiver IC as a detector is presented on page under the name “The Franzis thunderstorm warner“. The basic Arduino code is taken from Ramser-Elektro, and I modified it by adding an active Buzzer and some other small changes. The device is relatively simple to build and contains several parts: - Detector board - Arduino Nano microcontroller - four LEDs for a visual indication with resistors
