I already have a ultrasonic sensor that I purchased off of Amazon. However, it did not come with the cable that I need to plug into the GoPiGo, as mentioned in the 1st step of the Ultrasonic instructions: https://www.dexterindustries.com/GoPiGo/get-started-with-the-gopigo3-raspberry-pi-robot/4-attach-the-camera-and-distance-sensor-to-the-raspberry-pi-robot/
Where can I purchase this cable? Is it a special one that I can buy from Dexter Industries?
