Dentists agree that soft-bristles are a necessary component for an effective toothbrush. The use of nylon bristles instead of different kinds of animal hair completely changed not only the toothbrush, but also the way in which a toothbrush is made. During the manufacturing process bristles are folded over and put into place automatically. The bristles are then attached to the plastic body of the toothbrush with very small staples. Once the bristles are in place, the body and bristles of the toothbrush are put through a machine, which trims the bristles. At this stage there is an option for diversifying the toothbrush. As we wrote earlier in the “Life with the Toothbrush” different types of bristle design help improve dental hygiene. For example, the machine may cut in a “V-shaped” pattern to create a toothbrush more suitable for those who wear braces.

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.
