Quick and direty Sideway Warning system as sideway idea of Personal Photonics funded by the german ministry of education and science. Whenever something comes clother to you which you can’t hear (either because of hearing impairment or just because electrical cars are much more silent than the old one), a vibration on your arm should give you an hint that you might want to look to the side. 5 Vibration motors (actually only three are used (driven by an ULN2803), the other are backup if something goes wrong) are used in connection with three VL53L1X distance sensors. They are controlled with an Wattuino Pro Mini (3,3V), battery powered with an duall AAA battery pack. 3D printed housings snap everything on a wristband.
Due to sunlight and arm movement the system didn’t work that well in real life, but at least its fun to try out, we learned to connect several time-of-flight sensors at once (thanks to Lukas Ossmann for coding) and reused a nice Wristband for something looking cool (thanks to Sophy Stönner as designer).
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
