How do I solve the sensor’s abysmal abnormal output?
Problem description
When XIAO microcontroller is connected to the sensor signal output pin, keep printing unexpected values.
Sketch
I haven't sensor circuit diagram, you can machine translate and read the…

Is a PWM phase duration set with OCR1A a reliable way to communicate values to other Arduinos?
I am working on communicating 4 switch states across multiple Arduinos using only one pin. It must be as fast as conceivably possible.
Currently I have a master Arduino reading all 4 switches (multiplexing) and encoding them as 4-bit values: 0001 =…

Need help with debugging a heartrate/filter code (the heart rate calculation does not work)
The code below is a program that aims to apply the Pans-Thompskin algorithm to a signal attained from a ECG filter. The filter seems to work alright but it fails to blink the LED and collect a correct heart rate. The threshold might be the problem…

Seeeduino XIAO read PWM duration (period) using timers change Pins freom D2 to D1
I designed a circuitboard and need to proof the function.Therefore i have to modify the code to read from Pins D1 instead of D2.
Unfourtunatly i am not that familar with the high level programming so im not sure if i got all changes.
Basically all…

Seeeduino XIAO write and read PWM duration (period) using timers
I am trying to communicate between two Seeeduino XIAO (chip: ATSAMD21G18A-MU) by way of TCC capture using register timers.
Square wave pulse duration varies from 200ns to 4us.
I found these two code samples, and I am now trying to change them up to…

passive buzzer is drawing 500mA
I am having a ridiculously hard time trying to make a passive buzzer work correctly on my Seeeduino XIAO.
Here is the buzzer module :
Here is how I believe it works, assuming the SOT23 smd is a PNP transistor? :
I plugged VCC to a +5V rail, GND to…
