PLEASE IGNORE - I solved it 😉
Hi
I have spent literally all day building and rebuilding and testing things out but I am having a complete nightmare with Project 21 : Creating an LED matrix.
I have the following LED Matrix : https://cdn-shop.adafruit.com/datasheets/1818_KWM-R30881XUAB.pdf
I have tried following the mappings in the book to no avail - random rows and columns seem to light up. 
I have searched on Google and wired it up according the following matrix : https://fabienroyer.files.wordpress.com/2010/12/matrix.png - again, random lights
I followed this guide : http://layoftheland.net/archive/ART4645-2011/weeks7-12/LED_Matrix/How%20to%20Identify%20Pins%20on%20an%20LED%20Matrix.pdf - this showed me which rows and columns were controlled by which pins, so I changed the wiring accordingly but again - random lights.
Can someone tell me - is the matrix in the datasheet completely different to the one specced in the book ?  Or am I just going completely mad ?
Help !  [confused]
