PulseSensor Playground

This release fixes a bug when using a software timer to sample PulseSensor.

PulseSensor Playground

Changes to Speaker Example Sketch
This fixes the noisy tone issue #193
The tone interrupt collides with our interrupt, noisy tone is the result, and likely bad BPM values!

Use tone() function at your own risk!

In order to fix this problem and use tone() the Arduino core needs to be updated so that the tone library operates 'hands free' like the PWM library. Or, the PWM library needs to be updated to accept a frequency parameter to ensure a clean(er) note. There are some architectures upon which the Tone library might work: nRF52? ESP32?

PulseSensor Playground

This version updated the library to work with the latest ESP32 core files.

PulseSensor Playground

Further corrections to fix functionality of servo related code.

PulseSensor Playground

This release fixes a bug that showed up when using the Arduino Servo library when targeting AVR architecture.
Now you can use the Arduino Servo Library with AVR architecture again.

PulseSensor Playground

Major version update removing user's need to understand interrupts.

PulseSensor Playground

Support for Arduino DUE timer interrupts. Rock solid sample timing!

PulseSensor Playground

This release adds examples for the Arduino UNO R4 WiFi board.
PulseSensor_BPM_UNO_R4_LEDmatrix_Plotter.ino turns the LED matrix into a PulseSensor data plotter.
PulseSensor_BPM_UNO_R4_LEDmatrix_Heartbeat.ino will pulse the Arduino heart icon to your heartbeat.
