YouTube Video Link: https://youtu.be/oCWGiHfL3NY
Schematic: https://goo.gl/photos/wKB94DZT4ECusWmcA
This mushroom Lights project is built using a TCRT5000 infrared LED/transistor pair.
For the infrared LED, a 100ohm resistor is connected in series with +5v and the LED.
A 4.7k resistor connected in series between +5v and the emitter of the transistor.
Analog pin A1 (pin 2 on digispark) is connected to the emitter of the transistor.
I'm assuming the project is switched off at least once every 50 days so the millis() does not overflow back to zero.

IoT Manager mqtt device client https://play.google.com/store/apps/details?id=ru.esp8266.iotmanager
Based on Basic MQTT example with Authentication
PubSubClient library v 1.91.1 https://github.com/Imroy/pubsubclient
- connects to an MQTT server, providing userdescr and password
- publishes config to the topic "/IoTmanager/config/deviceID/"
- subscribes to the topic "/IoTmanager/hello" ("hello" messages from mobile device)
Tested with Arduino IDE 1.6.6 + ESP8266 Community Edition v 2.0.0-stable and PubSubClient library v 1.91.1 https://github.com/Imroy/pubsubclient
ESP8266 Community Edition v 2.0.0-stable have some HTTPS issues. Push notification temporary disabled.

I recently got one of those 8x8 LED matrices and I was playing with some Game of Life patterns when I found this pretty repeating pattern. I found it by starting with some random patterns. If you look closely you can see the pattern becoming a mirrored version of itself halfway through. Apparently the pattern doesn't repeat like this on an infinite grid but on this wrapping 8x8 grid it does ;-)
FYI, the LED matrix is a bicolor one (green/red) and has an I2C interface (http://www.adafruit.com/products/902). I'm using the colors as follows:
- newly created cells are green
- cells that are at least 10 generations old are red
- other living cells are yellow (simultaneously green+red)
It's hookup up to my Arduino Uno r3.
