+# Chiptunes on the Three Cent Microcontroller (Padauk PMS150c)
+
+This plays ["Bitshift Variations in C Minor"][bsv] by Rob Miles on the PMS150c.
+It needs no external components and is designed to run of a single CR927 lithium
+coin cell. The MCU detects automatically when it is plugged into a line input,
+and starts playing the music, and will go into a deep sleep once finished and
+disconnected. The project uses [SDCC]'s assembler and the [Free PDK] toolchain.
+
+Please check out the [full write-up] for more details!
