<h3>IR Beam Break Sensor Mounts</h3> <p>These mounts are designed to work with the <a href="https://www.adafruit.com/product/2167">Adafruit 2167</a> 3mm beam break sensor or the <a href="https://www.adafruit.com/product/2168">Adafruit 2168</a> 5mm beam break sensor.</p> <img src="https://cdn-shop.adafruit.com/310x233/2167-02.jpg" /> <p>The two-wire module is the IR LED and the three-wire module is the sensor.</p> <p>Red wires connect to operating voltage, either 5v or 3.3v.</p> <p>Black wires connect to ground.</p> <p>White wire connects to the input port.</p> <p>- When the beam is un-broken, the white wire will be at a logic high level. (close to operating voltage)</p> <p>- When the beam is broken, the white wire will be at a logic low level. (close to ground)</p> ------------ <p>Left and right mounts are mirror images of each other.</p> <p>The LED and sensor modules will easily snap into either one.</p> ------------ <p>This particular set of mounts was designed for use in a skeeball game.</p> <p>You can protect the sensors and wires from bouncing balls using <a href="https://www.homedepot.com/p/Everbilt-1-2-in-W-x-1-2-in-H-x-96-in-L-Aluminum-C-Channel-with-1-16-in-Thick-802657/204273938">1/2" x 1/2" C-channel aluminum</a>.</p> <p> - The mounts fit inside the C-channel.</p> <p> - Mount on the back of the playfield.</p> <p> - Position so the mounts are parallel and the IR beam passes through the center of the target hole.</p> <p> - Put the open side of the "C" toward the back of the playfield.</p> <p> - Cut a notch in the side of the aluminum so the LED and sensor can see each other.</p> ------------ <p>For ease of maintenance, I suggest using #8-32 x 1" machine screws and <a href="https://www.amazon.com/gp/product/B002KT11XO/">#8-32 threaded inserts</a>.</p> <p>The threaded inserts allow you to remove and replace the mount without stripping the screw holes.</p> <p>This is especially important if you are working with Medium Density Fiberboard since screw threads break MDF down to pulp so easily.</p> ------------ <p>SCAD files included so you can easily modify the mounts to work with your project.</p> Scott
