<\/a><\/p>\nPress the Start measuring steps<\/em> button to activate the pedometer and then start walking with your phone. You will soon see the Elapsed distance<\/em> value increase as you move around.<\/p>\n <\/p>\n Using the Designer, set a Horizontal<\/em> layout at top, and add a Label<\/em> and set its text to Set stride length<\/em>:, then add a Textbox<\/em> to its right.<\/p>\n Add another Horizontal<\/em> layout and add two buttons. Set one for the Start measuring<\/em> button and the other for the Stop measuring<\/em> button.<\/p>\n The next line is optional – a label has been added which is used to display the WalkingStep<\/em> event status.<\/p>\n Then add another Horizontal<\/em> layout with two labels – one to say “Elapsed distance:” and the second to display the distance traveled.<\/p>\n Don’t forget to add the Pedometer<\/em> component! The Pedometer<\/em> is located in the Sensors<\/em> section of the Palette<\/em>, and when dropped on the Designer View<\/em>, appears as a non-visible component below the screen area.<\/p>\n The components are labeled as shown here:<\/p>\n The NumbersOnly<\/em> property checkbox of txtStrideLength<\/em> is checked to limit the input to numeric values.<\/p>\n Setting up the Designer View<\/em> is harder than writing the app!<\/p>\n The Pedometer<\/em> is started by – surprise – calling its .Start<\/em> method.<\/p>\n The Pedometer<\/em> is stopped by calling its .Stop<\/em> method.<\/p>\n The .Reset<\/em> method resets the distance counters to zero.<\/p>\n As you walk, the Pedometer<\/em> component generates two events – either SingleStep<\/em> or WalkStep<\/em>. The distance<\/em> parameter holds the estimated distance traveled and is the same as the Pedometer.Distance<\/em> property.<\/p>\n Access the source file at the MIT App Inventory Gallery<\/a>.<\/p>\n In addition to hundreds of posts and examples on this blog,\u00a0I have several e-books available from Google Books, Amazon and other outlets. The books cover topics that are far too large to cover in blog posts, especially for\u00a0Volume 3 – Databases and Files<\/em><\/strong> and Volume 4 – Graphics, Animation and Chart<\/strong><\/em>s<\/strong>. Volumes 1 and 2 are intended for those just starting out with App Inventor.<\/p>\n Visit the books page<\/a> for details on each book, sample chapters, where to buy – all are very inexpensive.<\/p>\n Also, use the Search<\/em> box in the left column of this web site to look for other examples to help you with your App Inventor programming!<\/p>\n The pedometer uses the phones motion sensors (accelerometers) to identify when the phone (or tablet) is being carried by someone that is walking – and uses this to measure the number of steps you take as you walk. When calibrated to the length of your stride, the pedometer provides a way to estimate the distance … Continue reading Using the Pedometer in MIT App Inventor<\/span> Designer View<\/h2>\n
