Using a magnetometer and an lcd screen together??

Other Hardware Sensors
1

Hi so this is pretty much what I have:

  • arduino redboard from SparkFun (much like the Uno board)
  • HMC5883L Magnetometer
  • 1602 LCD Screen
    I am trying to get the magnetometer and lcd screen to work together at the same time, but I am confused on how I can accomplish this if both components need to be connected to the sda and scl pins (A4 and A5 on my board).. Do I need 2 arduino boards? Can it be done with one? Can I use other pins or are those reserved for sda and scl? I am pretty new to Arduino and don't know much about how this i2c communication works with multiple sensors.. I am currently only able to get one working at a time because I'm not sure how to put them together

More than one device (up to 128) can be connected to the same SDA and SCL pins, if they have a different I2C address.
Sometimes the address is hard coded into the device, sometimes you can set a range with jumpers or solder bridges.
