When in doubt of your posture just use the Bad Posture belt to get notified of your bad posture. This is enabled with an Arduino board, a Wave Shield from Ladyada, a flexi bend sensor and a push button! The bend sensor is fitted in a belt together with the rest of the electronics. By placing the bend sensor at the back of the belt I can detect when the back is arched and not. With the push button I set the desired arche of the back and “calibrate” the back and the belt to remember this value. When the back is more arched than this value the Wace Shield makes its sound!
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
