Really nice and detailed post about this DIY ultrasonic parking sensor. Nice work! Via ch00ftech Industries.
No, it’s not mine. One can dream…
Background and motivation
It should come as no surprise that I really really want a Tesla. Or really any Electric Vehicle for that matter. The only problem at the moment is that my daily commute takes me 20 minutes on foot each way, so I really can’t justify buying a car that will spend most of its life parked in a garage or parked in Seattle traffic.
That’s why I have to live vicariously through other people, and why I got super excited when I learned that my dad put down a deposit on a new Model S.
It hides it well, but the Model S is a massive car with a length of 196 inches and a weight over 4700 pounds. My dad originally planned on parking the car in his driveway, but when it came time to install the charging port, he opted for the garage instead. The only problem was that his garage only offers about six inches of clearance to be shared between the front and back of the car.
This predicament gave me some great gift ideas. With the holidays fast approaching and all of the other projects that I wanted to finish before heading home, I originally did a quick Amazon search for ultrasonic parking sensors. Sadly, most of them “bottom out” at a fairly reasonable one foot. I couldn’t find any that would drop to the two to three inch range.
So I added another project to my list and got to work!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
