Perhaps I don't necessarily need to use the same pins
Both the sensors you quote are using I2C. So they both use the same 2 pins (SDA, SCL) to communicate. You can put many I2C sensors on those same pins, they each have an address to know which sensor is receiving/sending data to the master (here, your arduino).
Look for a tutorial on I2C first.
Thanks I get it now
Hi, I complied your code for NRF51822 chip but I am getting the following errors at compile
