This is an odometer and speedometer for bicycles which keeps track of distance traveled (in km), time traveled in hours, minutes and seconds, average speed (in km/hr) and maximum speed attained during any one minute period (in km/hr). It can keep track of a maximum 99 laps/cycling periods. It can be built with parts from the Arduino Starter Kit, with the exception of a Hall sensor and enclosure box which need to be purchased separately.
I cycle quite a bit to stay in shape and want to know how far I cycle, average and current speed, etc. I can not justify buying a device that does this (with probably many features I don’t need!) so I decided to build this myself. I did not look to see if someone else created something similar as I wanted to challenge myself and stretch my newly acquired Arduino skills!
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.
