Semiconductors can do wonders! With a transistor, you can switch a higher voltage with a low voltage. A Schottky diode controls the flow of current only in one direction, like a traffic policeman. With a regulator, you can reduce the voltage to a certain value and it maintains it at the same level regardless of changes in the input voltage. In this category, you'll find various components. Are you a beginner in tinkering and don't have order in electronic components? Read our article, which will guide you through them.
