This is on digital pins 10,11,12 and 13 on the Uno and pins 50,51,52 on the Mega.  On both boards, pin 10 is used to select the W5500 and pin 4 for the SD Card. These pins cannot be used for general I/O.</pre> </div></div> <p>We are using currently using pin 4 to read blue shutter close switch state, that may be the root cause of the board misbehaviour.</p> <p>We need to recable pin 4 to another one and check if it solves the problem.</p> <p>pin 4 has been switched to pin A4, it's working fine now.</p> Development Rank 0|u0009r:zzzzy4 Sprint SM1-2019 E Story Points 2.0
