Greets makers, im working with 3 sr04s and would like to remove the breadboard from the project. If i use the digital output for power to each one, how can i ground all 3 with just one gnd pin?
Connect the sensor gnds at at one point and connect this to the Arduino.

Thanks weed. Do i need to put in a resistor before i ground them?
The gnd connections should all simply go to gnd without any R.
