  • 5v would not be a sufficient to power an arduino with the heating pad. You would need about 30V to get around 45C. It’s just not feasible to power one pad with 5v

  • You cannot wash these in a washing machine, they will not survive the process. Also, you would need quite a few pads to feel the heat produced through fabric.

No public wish lists :(
