Power Driver Shield Kit

HI
is there any precaution to have when use something like:

Solenoid valve like http://www.ceme.com/prodotti_2.php?id_liv=1&id_liv2=4&id_liv3=8&id_prod=47
and this Heating Pad - 5x10cm https://www.sparkfun.com/products/11288 ???

On Power Driver Shield Kit from sparkfun https://www.sparkfun.com/products/10618??

it seams it don´t flow properly.

I´ve solder one wire from VIN to 12v on shield to get the power from arduino adapter, is it bad?

Want to make build my egg incubator :grin:

thanks for u reply, really don´t have any idea for this...

]:smiley:

peace

the solenoid valve operates on 230Vac according to the data sheet. You can't use that board for the solenoid valve, but should easily drive the heater.
