+
+An [Arduboy] is an Arduino based 8-bit handheld console.
+
+<img src="/assets/images/posts/hrdlr-arduboy/hero.jpg" width="620" />
+
+I picked one up and decided to make a hurdling game (again).
+
+## Graphics
+
+I used [Aseprite] to draw the graphics which were saved as PNG files then converted to C header files using [mksprite].
+
+Below is an example of the first from of the [coin][4].
+The comments are added my [mksprite] to make it easy to tell what frame you're referring to and aren't required.
+
+For example the first frame of the [coin][4] looks like:
+
+``` c
+const uint8_t PROGMEM coinFrames[][4] = {
+  /* Frame number 0
+       ##
+      #  #
+      # ##
+      # ##
+      # ##
+      # ##
+       ##
+
+  */
+  {0x3e,0x41,0x7d,0x3e},
+```
+
+## Demo

+## Code

+Fair warning though, I don't really know C or C++.
