Library Installation

Note: This example assumes you are using the latest version of the Arduino IDE on your desktop. If this is your first time using Arduino, please review our tutorial on installing the Arduino IDE. If you have not previously installed an Arduino library, please check out our installation guide.

We've provided a library for the SparkFun Lightning Detector that configures every available setting the IC offers. Some of the features include modifying the sensitivity of the antenna, whether you're inside or outside, fine tuning when the IC triggers an interrupt, or modifying the resonance frequency of the antenna. You can search the Arduino Library Manager for "SparkFun Lightning Detector", or you can click the button below to get the library and install it manually. Finally, you can also download it manually from the GitHub Repo.
