Hi there..., I´m working on project using Arduino Uno and Arduino Motor Shield r3, was looking over internet some documentation but it´s realy poor.
I want to use TWI IN for hx711 for weight sensor, I dont find documentation about how to declare pins on sketch.
If some body have this information, I will realy appreciate share it.
Best Regards

A quick Google search for HX711 Arduino turned up this:

"The example code has **DAT and CLK **hooked up to pin 3 and 2 respectively, but this is easily changed in the code. Any GPIO pin will work for either. Then VCC and GND just need to be hooked up to 2.7V-5V and ground respectively on your microcontroller."
