Flickering LED Tealight Candle

There are plenty of candle-flicker LED projects out there, but I was looking for one that had a few additional properties:

- A more realistic flicker based on a normal distribution of light intensities instead of uniform random numbers
- A candle that would respond to the environment
- Something that fit in a standard Yankee Candle (R) tealight candle holder

The thing I created uses an ATTiny85 to generate a binomial distribution of random numbers that are then fed to a PWM output that drives the LED intensity. The LED is the Adafruit Sequin LED that is compact and comes with its own resistor for ease of use. I've added a light sensitive resistor that is connected to one of the analog inputs of the MCU, which triggers a change in the LED flickering when someone moves their hand over the object.

**As an added bonus** I connect the battery back (in the base) to the electronics (in the cap) through some copper tape along the inside of the candle, so it is possible to switch
