Arduino BLE Cycling Power Measurement #Arduino #Bluetooth #BLE

Tea and Tech Time noted a need given more time spent inside:

I needed to find a way to exercise. I decided to pick up a cheap folding indoor bicycle that had a way to sit back and had some different resistance values. I didn’t want to spend a lot of money so the bike only has a very basic interface.

Researching and investigating the bicycles sensor method, it turned out to use a simple magnetic sensor with a spot on the fly wheel that was de-magnitized. As the pedals rotated, the magnetometer was able to pick up the sudden dip as the de-magnetized portion passed by it, and that increasing the resistance, the maximum amplitude decreased in noticeable increments.

I needed a dedicated sensor and a platform to perform the conversion algorithm as well as host the Bluetooth Low Energy Service that would communicate with the virtual cycling app. … I went rummaging through my dev-board bin and came up with this little Arduino Nano 33 BLE Sense board.

See how the data was sensed and sent via the BLE Cycling Power Service in the blog post here.

 

 


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.
