We have a library of Proto-PIC-created Tutorials for Arduino, Raspberry Pi, BBC Micro:bit and more, that cover a wide range of electronics topics, all designed to aid in the learning of electronics and coding.
What is a Light Dependent Resistor (LDR)? An LDR is used to detect light levels in a wide range of household and industrial projects, such as security lighting. They are in essense a variable resistor, that varies its resistance as the light intensity increases or decreases. In the dark or at low light levels, the …
What is an FSR? You know when people say the clue is in the name… Well, sometimes it really is. A Force Sensitive Resistor, or FSR as we’ll call it, is a resistor that changes its resistance with force. When you press, stand, or hit it, its resistance changes. FSRs come in a wide variety of …

Let’s start by understanding a capacitor. A capacitor works by storing energy electrostatically in an electric field. What is capacitance? Honestly I’m asking myself that too, so let’s try another way of thinking about it. Let us start out with an analogy: you might know that capacitors are like batteries. In some ways this is …

Before we can answer that we need to know: What is resistance? Let us start with conductors and insulators. Basically conductors allow electricity to flow and insulators stop electricity. Well that’s a rather simplified view, because there is more to it. For example air is normally an insulator, but with a large enough voltage it …
