Visual – light, color, and vision
Materials that glow and light up always add an element of excitement or wonderment to a wearable. The good news is that we can add light to our wearables in many ways!
There are a few ways we can enhance our projects with both light and vision. In this section, we will look at the following:
- LEDs
- NeoPixels
- EL wire
- Display screens
Throughout this book, we have played with LEDs, so we already know about these in a basic way. Let’s start with an overview of LEDs, then explore other ways we can add light to our wearables!
LEDs
An LED is a diode, as we’ve seen previously. Since it’s a diode, electricity travels through it in one direction. The color of the light is determined by the energy gap distance inside the LED. They come in a huge variety of sizes, shapes, and colors. LEDs can also be ultraviolet and infrared, so we can’t see the light, but we can use them to control other devices...
