Hi! I'm using an Arduino Uno R4 Wifi with a heart rate sensor (DAOKAI MAX30102), but the serial monitor suddenly decided to write wrong values. When there's no finger on the sensor, it writes -1 (which is correct), but when there's the finger it writes 0 or a wrong value (like 20). Can anyone help me?
