About: Hi

This thermal pad could be used for any type of application. I made it at home during winter time to preheat my tea or coffe, because after some work it always getting cold.

Supplies

1unit Arduino UNO

1unit Mutifunctional POWER SHIELD 6+6 T800

1unit Arduino UNO prototiping PCB

1unit Dalas one wire digital termometer DS18B20

1unit Some wires, resistor 4.7K

1unit Aluminium sheet 100x100x10mm

1unit Some bolts
