  • I’m driving one with a 16V supply. I drilled a hole in a quarter and bolted it to the 7805, and it’s been stable for at least 2 weeks.

  • In your example code, you do this:
    void loop()
    {
    char msg;
    if(digitalRead(8) == LOW){
    char
    msg = “1”;
    Writing data to an empty, unallocated pointer?!?! Isn’t that asking for a segfault?

No public wish lists :(
