Breadboards make this type of prototyping work simple; they should be your second best
friend (just don't let the data sheets know)! Next up, insert the jumper wire. In standard
mode you need to feed the sensor power and provide a ground. So connect pin 1 to ground
on the breadboard and connect pin 3 to your 3.3 V source. You can see how I have inserted
my jumpers in Figure
