A vaccine is right around the corner but we still need to be vigilante untill one has been widely distributed. Clear simple wearable to keep your personal space from barney.nicholls on Instructables:
Hi, this is a project that I put together with the idea of creating a wearable battery-powered device that would easily show another person whether they were entering inside the current recommended social distance of 2 meters.
This is an Arduino based project that uses an ultrasonic distance sensor and then turns on either a green led if there is nothing sensed within 2 meters or a red led if something is detected within that range. This is a just for fun project and although the distance sensor is fairly accurate I’m afraid that soft people don’t necessarily give as good a return signal as preferred when bouncing sound waves off them 🙂
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.
