 She was built in my beginnings and needs an update. She burns through 3.3V batteries like crazy.

+=== Simple blink ===
+Wire two leds to pin 0 of atTiny85. Wire two 220 Ohms resistors between each LED and GND.
+Each LED should draw a max of 20 mA from the pin which keeps it just under the 40 mA limit.
+If you want to wire more LEDs, look into other techniques or use other pins.
+++++ Simple arduino code |

+int led = 0; // LED pin
+int brightness = 0;
+int fadeAmount = 5; // points to fade LED by
+void setup()
