In this article I would like to show you a small project on how I built an LED aquarium light from various leftovers. The brightness is automatically controlled by an ESP32 microcontroller.

How can you control higher loads such as LED strips with the ESP32 when a single GPIO pin can only deliver a few milliamps at 3.3 V? In this article, I take a practical look at different transistor solutions for switching higher currents with the ESP32. I compare a Darlington transistor with three MOSFETs and show, which types are suitable for logic-level control.
