| Dec 20, 2018 at 3:50 | comment | added | M.Schindler | They are connected to the Arduino Micros SCL and SDA pins. I did have both devices working before I shorted the device. I would like to know why when one device is bad (or not powered) on I2C, it screws up the other devices. | |
| Dec 20, 2018 at 3:47 | comment | added | Jaromanda X | so ... you connect the scl/sda on the "pressure sensor" to the MPU6050 using 1k resistors? why? and how are these two components connected to the arduino? as a schematic, that leaves a lot of unanswered questions | |
