IR Sensors
The bottom of your PCB should now look like this:
Next you will be installing the 3 IR sensors on the top side of the board, and soldering on the
bottom side.
Note the corner insertion pin on the sensor. It fits
inside the mount hole on the PCB. The body shape is
also printed in white on the PCB for proper installation.
Slide the 4 legs through the PCB, and push the IR
sensor all the way down. The insertion pin will
mate with the hole in the PCB.

Mind the notch!
Don’t press on the 2 LEDs. Hold the sensor
from the sides. If you press too hard on the
leds they may break.
A properly mounted sensor should look like this before soldering.
If the bottom of the IR sensor plastic housing
has a deformity that stops it from laying flat
on the PCB, trim the plastic with your snips,
or a hobby knife.
