John,
     I am of the same opinion about Mike as you. I get nervous mixing 5=20
and 3.3. 1.7 with zero ohms equals what ever the power supply can=20
deliver. Mathematically it equals infinite current. Not good. Lots of=20
smoke. I suspect as much about the Pi. So what is a good book about=20
learning how to program the Arduino in C? Mike? I agree about being=20
alive. When I was a kid it was really hard to find things to keep me=20
occupied. I wish I had this much stuff when I was a little one.
Thanks,
rich!
