Understanding electricity
Let’s start with electricity basics to begin our journey of making wearables. We will cover the following:
- What is a circuit?
- Resistance
- Voltage
- Current
The preceding list highlights three main properties that we need to understand to build our circuits: resistance, voltage, and current.
These three properties connect and have a relationship called Ohm’s Law. It’s important that we understand these properties to help us build and fix our circuits. Also, when you have finished the exercises in the book, you will have the confidence and skills to create your own projects. Let’s explore them in detail, starting with circuits.
What is a circuit?
A circuit has a start point and an endpoint with an electronic component in between. It forms a loop. This allows electricity to flow. Between the start point and the endpoint, there can be many other connections. Circuits can consist of components such as...
