CIRCUIT #1 - Your First Circuit
Your RedBoard runs on 5V. is is the power that will be supplied from your computer via USB and
will be the driving force behind any components you use in your circuits. By plugging your RedBoard
into your computer, you are supplying it with just the right voltage it needs to thrive! 5V can’t hurt you,
so don’t be afraid to touch anything in your circuit. You can also power the RedBoard through the
barrel jack. e on-board voltage regulator can handle anything from 7 to 15VDC.
