playing with ArrayBuffer and led matrix... i'm confused

Hi Mike... I'm relieved that things are 'relatively' ok for you. I'm glad you spoke up. I'm totally aware that life can take turns hat change almost all things. I'm really happy for you that you are still around, 'back' at work teaching, and hope - may be one day - Espruino will will resume happening. As you may have seen from my posts, I built the display board for the light, electronic and code part, and I even added some game paddles - just switches for a reaction game I actually played w/ my grand kids. Being busy with other things I did not make it to other parts of the game board you had mind or any other one yet. But anyway, it was a pleasure to have been inspired by your ideas and challenged to find a solution. I wish you well... and soon kids / adolescents back in school again... - ao
