 ====== Jozéphine ======
-===== Résumé =====
+A creepy doll with red leds instead of eyes.
-A creepy doll with red leds instead of eyes.
+{{projets:jozéphine.jpg?400}}
-She needs an update.
+The eyes blink 3 times in a cycle when she is moved around.
+She was built in my beginnings and needs an update. She burns through 3.3V batteries like crazy.
+=== Official GitLab Source ===

+==== Arduino snippets ====
+=== 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 |
+<code c>
+int led = 0; // LED pin
+int brightness = 0;
+int fadeAmount = 5; // points to fade LED by
+void setup()
+{
+  pinMode(led, OUTPUT); // init led
+}
+void loop()
+{
+  fadeEyes(); // blink the eye thing
+}
+void fadeEyes()
+{
+  analogWrite(led, brightness);
+  if (brightness == 255)
+  {
+    delay(1500); // stay a bit on full bright led
+  }
+  brightness = brightness + fadeAmount;
+  //reverse direction at start & end of fade
+  if (brightness == 0 || brightness == 255)
+  {
+    fadeAmount = -fadeAmount;
+  }
+  // wait 30 miliseconds to see changes
