Project Description
Mobile RPG is five ATtiny85 microcontrollers playing their own RPG characters with a primary MCU acting as GM. Its a fun exercise in autonomous role playing.

Here, there are five (5) ATtiny85-20SU connected to USI/SPI each reading from an analog LDR-R divider for randomness (if there's one thing used a lot in an RPG game is randomness). So, sampling the ambient light at any given time and running it through the ADC for a digital value is used for this purpose. There is also a 0603 Green LED on-board that lights when inserted into the card edge backplane.
