This is an Arduino tutorial on how to detect lightning from far away.
In this tutorial, we will build a lightning detector using an Arduino Uno, a few resistors and some jumper wires. 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. 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.
