That's right

Capacitors:

yet there are a few things to watch for

Capacitive touch sensing works by detecting when a person (or animal) has touched one of the sensor electrodes

5V tolerant inputs - Hook up your Pi to accept input from 5V systems (like Arduino Uno/Leonardo or 5V Trinkets)

Adafruit DotStar Digital LED Strip - Black 144 LED/m - One Meter kit That's rightThese fancy DotStar LED strips are a great upgrade for people who have loved and used NeoPixel strips for a few years but want something even better. DotStar LEDs use generic 2 wire SPI, so you can push data much faster than with the NeoPixel 800 KHz protocol and there's no specific timing required. They also have much higher PWM refresh rates, so you can do Persistence of Vision (POV) and have less flickering, particularly at low brightness levels.
