Step 5: Install and Calibrate
IMAGE TWO: Install the PHOTO RESISTOR under the bottom rack in the washer where, if someone blocks too much light from above (IMAGE THREE) with a huge dish, the sensor will say, "Hey! That also means you're blocking too much cleansing water from bellow! How will those poor cups up top get the bath they deserve?! I'm sounding the ALARM!"
IMAGES FOUR & FIVE: This is where the calibration thing comes in. We had to tweak the 'int threshold' value several times before the sensor worked inside the washer. The number can be quite different! From the work bench to the dishwasher the value changed from 30 to 500! And don't forget, the TACTILE SWITCH has to be depressed to run the program.
Note: Ideally, the light in image three would turn ON via the TACTILE SWITCH and OFF when a properly loaded (a.k.a. no alarm) dishwasher began doing its thing. For the demonstration, a camping headlamp was used because it was the only thing bright enough, and small enough to run the program well. We hope you understand the concept in spite of our having to adjust on the fly.
