Example applications include using extra channels on an RC receiver or servo controller to turn on lights

which results in drive-coast operation (also known as fast decay )

so the effective minimum detection distance might increase (ie for distances that would result in output voltages above your supply voltage

The following command will turn the Red led off and make the I/O lines high so they can be used as inputs:

The SparkFun Power Supply Sample Kit provides you with a sampling of the power supplies that we offer to power your next project. Included in this kit are four different wall adapter power supplies, two at 5V, one at 9V, and one at 12V. * **USB Wall Charger 5V, 2A**: USB as a power connection standard is common these days, but you don't always have a computer on hand
