Soft circuits
We’ve been learning about the importance of testing our circuit on a breadboard and what happens when connecting components in series and parallel circuits. Now, let’s look at LEDs, conductive threads, and conductive fabrics. Once we understand their foundations, we can create a soft circuit.
LEDs
LEDs come in many sizes and types (Figure 2.20). They can suit a huge range of purposes. It is a good idea to have a look online at some of the LEDs you can get so that you don’t limit yourself to just using the most common ones. In this chapter, the LEDs are 5 mm, but they can be as small as less than a millimeter. They are low power, have a long lifetime, and are robust.
Some common places where you’ll see LEDs are control panels, computers, traffic lights, car lights, electric toothbrushes, and streetlights. LEDs have a range of colors, opacities, and light intensities. The higher the voltage the higher the lumen, and the greater the...
