How to control an LED based on the ambient brightness with the ESP32

Leave a Comment / esp32, NodeMCU, PlatformIO /

Introduction In this article, we’re going to build a fairly simple project: a system that controls the brightness of an LED based on the ambient brightness. In practice, the lower the ambient brightness, the more the LED lights up and vice versa. For the detection of ambient light we will use the well-known BH1750 sensor
