Arduino Rowing Computer with MKR1010
I broke the rowing computer that ships with this cheap Amazon rower I bought secondhand.
I'm writing a new one in Arduino that will drive an LED screen with the inputs of a Polar H10 HR Monitor and the original stroke sensor that ships with the machine.
- The Arduino board is the MKR1010, note that it's 3.3V unlike most Arduino
- HR Monitor: https://www.polar.com/us-en/products/accessories/h10_heart_rate_sensor
- LCD https://www.buydisplay.com/small-size-arduino-code-lcd-20x4-i2c-character-display-wide-view-angle
- This uses the I2C connector that ships on the board to reduce number of digital pins needed
So far I only have the Polar and the Arduino, this code will connect to it (and many BLE heartrate sensors with minor modifications)
This is a very rough draft.
- HR Measurement defined bluetooth spec uses this flag to tell you some interesting shit:
