The holiday season is here, and with it comes the joy of decorating and spreading cheer. One way to make your celebrations truly stand out is by creating your own custom Christmas lighting. A DIY project brings a personal touch, turning ordinary lights into something unique and memorable. Besides the festive fun, it's a creative way to learn and experiment with technology.
Soil moisture modules are a simple and friendly way to check how wet your soil is using a pair of probes and a small control board. They offer two outputs you can use with Arduino: an analog signal that changes depending on how wet the soil is, and a digital signal that flips on or off when the moisture crosses a level you set with the onboard potentiometer. The whole setup is compact, cheap and very popular for plant care projects, garden automation and basic hobby experiments.
