Tutorial how to transform your ordinary 12V spot light into a smart light. Many smart LED lights on the market today can be expensive and require connection to a Wi-Fi network. However, with DIY solution, you'll be able to control the intensity of your light with ease, without breaking the bank.

Video shows the process of designing a circuit based on the XL4015 buck converter, which is highly efficient and capable of handling up to 5A of current. By modifying the feedback loop and integrating a digital potentiometer, we'll achieve precise control over the light intensity using a digital inputs.

Follow along with sketching a schematic and creating a board using Eagle in first part, then move on to assembling and soldering the components in second part. Video provides detailed explanations of the circuit design and demonstrate how it works in action.
