Hi together
I try to make the Weather Shield work on a Arduino UNO Wifi. Currently, I get the error message "I2C communication to sensors is not working. Check solder connections". As written for the HTU21D humidity sensor, I will have to remove the I2C pull-ups if there is any other I2C device connected. The Arduino UNO Wifi has already pull-ups because of the internal I2C communication. Therefore my question: What is the best way to remove the pull-ups of the Weather Shield? Remove the R2 and R3 resistors???
Best regards,
Mico
