I want to connect the HC-SR04 Ultrasonic sensor to gopigo, using a grove cable.
The grove cable has these colors: black red white yellow
What is the correspondence to the ultrasonic pins:
vcc (this should be red? )
ground (this should be black? )
I guess i need to cut this cable on one hand to connect to the proper pins
Please let me know. Do you have any documentation about this.
