PortalATtiny

Create a portal from Valve's video game with an oval mirror and a NeoPixel led strip.

Hardware

You need the following hardware:

Microcontroller (Arduino Nano/ESP01s/Digispark ATtiny etc.)
5V power supply (for the NeoPixel)
RGB LED strip WS2812B (5V, GND and Din pin)
optional: 470 ohm resistor to protect the microcrontroller
optional: 1000 µF capacitor to stabilize
optional: 3.3V Step Down Module if 5V is too much for your controller (like the ESP01s)

Setup

Connect the hardware:

Power pins (+5V and GND) of the led strip with +5V and GND of your power supply.
Din pin of the led strip with a digital pin of your microcontroller (optionally via the resistor)
The microcontroller's 5V/3.3V/VIN and GND with the power supply (or the Step Down Module)
(Put the capacitor to 5V and GND of the power supply)ŵ

Firmware

Open the ino file inside the Arduino IDE. Before you flash the code install the library Adafruit NeoPixel by Adafruit and do the following configurations:

Number of leds

Change LEDS to the number of your leds.

#define LEDS 43

Led color

Per default the color for the orange portal is used. For the blue portal change it as follows:

#define RED 0
#define GREEN 0
#define BLUE 255

Per default pin 3 is used to control the NeoPixel. Change it if you use another one:

#define PIN 3
