‘Parking Buddy’ is a Visual Warning System for Your Garage #Arduino
Great, simple project from shiftline over at Instructables – the 24-LED NeoPixel ring goes from green through yellow to red and eventually flashes all-red as your car comes into the garage and should proceed no further. This quick video demos the project in action:
Have you ever wanted a high tech parking assistant? Its time to put away your hanging tennis ball and get into the 21st century with an electronic parking buddy. This project uses an ultrasonic sensor and a nexopixel ring to light up and complete the ring as your get closer to the sensor.. When you are at your maximum distance (closeness) the ring will be full, (fades from green to yellow.. If you get to close it will flash red to warn you your in panic mode!
NeoPixel Ring – 24 x 5050 RGB LED with Integrated Drivers: Round and round and round they go! 24 ultra bright smart LED NeoPixels are arranged in a circle with 2.6″ (66mm) outer diameter. The rings are ‘chainable’ – connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you’re ready to rock. Read more.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
