The Ben Heck Show

IoT on Wheels - Smart Bike (1) (7x28)

:

Ben, Karen, and Felix are joined by Bob Baddeley, a local electrical engineer, for their IoT on Wheels Design Challenge project. Ben works on the mechanical design in Autodesk Fusion 360, Felix gets started working with the Nucleo Board, and Bob shows them how to connect Bluetooth expansion board to an iOS app. The team is working on a device that fits onto your bicycle and communicates with your smartphone over Bluetooth LE to pass information back and forth. It will be able to send a message to an administrator if you hit a pothole, there will be an alarm built into it, vibration and tilt detection, and more. This project is for the IoT on Wheels Design Challenge on element14. They'll be using the ST microelectronics Nucleo64 along with a Bluetooth expansion module. Felix brought in a bicycle for the team to base their measurements on. Once they know how much room they have to work with Ben goes to work drafting a design in Autodesk Fusion 360. It won’t be a one size fits all solution, it will work for this Design Challenge as it will be specific to this build. They won’t be printing the tubes they are drafting, but the drawing will give them a good reference for their build. With the Fusion 360 symmetrical extrusion, you specify length from center, not the total length. After he’s done they’ll know where to put the surface of their object and where to put their mounting clamp. Felix gets started working with the Nucleo Board by going to the ARM mbed OS developer site. Clicking on compiler will take you to the online integrated development environment so you can begin working with your programs. You could install IDE’s and compiler toolchains but the online development saves you from the hassle because online development handles all of this for you. He firsts walks you through selecting the Nucleo-L476RG (Nucleo 64) as your hardware platform and then gets a blinky example going. Coding examples such as the blinky example are common whe
