Hello, I recently bought these heating pads https://www.sparkfun.com/products/11289
For my arduino uno r3. However I literally have no clue how to hook them up to the arduino uno and the code to use them;). So what I'm asking is, how can I hook them up to the arduino and the code so that it can power the heat pads until I unplug the heat pads (in other words, always on).
Thank you for all the help!:)
