Slipper Finder

Late dark in night, when you have to get up for any reasons, it'll be hard to find your slippers without light. But if you turn on the lights you may disturb your roommate. In this situation, the design and the device you're looking at right can solve your problem in the late late night. It's really easy, perfectly designed for Arduino starters to learn how to work with ultrasonic sensors.

You'll need......

1 Ultrasonic sensor

3 LED Light Bulbs

3 Resistance

Long Jumping Wires

2 Short Wires

1 bread board to work with

1 Arduino Board

You'll need......

1 Ultrasonic sensor

3 LED Light Bulbs

3 Resistance Long Jumping Wires

2 Short Wires

1 bread board to work with

1 Arduino Board

Pictures are provided if you need any visual help on how to connect the wires and the ultrasonic sensor.

First, make your bread board just like the picture, connect the wires and special devices

Now, the steps...

1. There will be 4 legs on the ultrasonic sensor, "Vcc," "Trig," "Echo," and "Gnd."
2. Vcc is the positive end, so connect it to the positives (See picture)
3. Connect Trig to Pin 6, and Echo to Pin 7.
4. Gnd is negative, so connect it to the negatives.
5. Use Digital Pin 11, 12 and 13 as the positive ends for the LED lights. Connect the positive legs of the LED lights to these pins individually.
6. Then use the resistances to connect the negatives to the LED lights.

Here, you can choose to keep the LED lights on the bread board to keep your working place more organized, because if you connect the long jumping wires now, it may cause a mess, wires may get tangled together😂.

The coding isn't hard,

I'm just gonna put what I did here, so you can either copy or try on your own and make mine the answer. You can change some variables youself to fit your situation.

If you've made it here successfully, then congratulations!! You're done with the device! Now you can connect the LED Lights with long jumping wires so it can reach the edge of you bed and show where your slippers are. No more finding slippers in the dark with this device.
