Step 12Finished Making!
Open up the Processing sketch, move the front wheel so that the magnet passes the sensor and you should see the graph come to life!
You current speed will also be displayed on the 16x2 lcd!
NOTE: I couldn't have completed this project without the help of Adam O'Hern's work with the Arduino and Processing code! My slight modifications do not amount to the time and effort he has put into building the original code! Adam - Thankyou!
I hope that this instructable inspires you to create your own arduino based cycle computer! :)
