Grumpy_Mike:
Put an Arduino under a hat.
Hit the hat with a hammer many times.
Remove the Arduino from the hat totally undamaged.
Good trick, is that with a clone or genuine Arduino?
What model Arduino?
Can you post your code for that between code tags
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
Thanks.. Tom..
