Work in progress from alan_dewindt on hackster.io:
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!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
