NEW GUIDE: Toy Car Speed Timer #AdafruitLearningSystem #3DPrinting
Find out how fast your toy car is.
Use two pairs of IR break beam sensors and some 3D-printing skill to build a Toy Car Speed Timer block to adjoin to your 1/64 scale toy race car track! A Feather M0 Basic calculates the difference in time between the two breaks in the pairs of IR sensors and displays the value on an OLED display. The unit is battery powered so it can be switched on and off quickly without running a main power line to the circuit for use in your track design.
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.
