Hello
I am trying to connect some ultrasonic distance sensors to my Arduino robot. I am having a little trouble because there aren't any markings on the pins etc. On the control board I have 8 3-pin connectors marked M0-7, are these the connectors I should be using and if so which pin is which.
Thank you
Rob
Sorry, but my crystal ball is broken at the moment :o
Which Arduino robot are you working on? (a link, picture) etc. will help a lot in diagnosing your problem.

He probably means "the Arduino robot" - https://www.arduino.cc/en/Main/Robot
At least - when people say "the Arduino robot" - I always think they mean the official one, barring any other reason.
/did you know there is also an official Arduino 3D printer...?

I have seen different "Arduino robots" so that's why i'm asking.
Yep, i know their printer, the Materia 101.
I'm in the process of building a self-sourced Ultimaker 2 Go clone at the moment.

Well, i have been looking at the schematics available for the official robot, and i cannot see any headers marked M0-7 - The silkscreen also says prototype, so i guess they changed something and forgot to update the documentation?
Although there is some 3-pin headers around the 'bot, which are connected to a 74HC4067 Multiplexer IC, which in turn is connected to PD4 on the main processor.
I googled Arduino robot m0 and found this:

Thankyou, the 3 pin headers are the connectors I'm looking at. Futher to this, I want to connect ultrasonic distance sensors to the headers. Now in the example sketches (PING), the sensors they use are SEN136B5B which I believe are obsolete, and so I'm using the HC-SR04, the main obvious difference is the number of pins. On the SEN136B5B, it has 3 pins, and the trigger and echo are carried out via the same pin whereas the HC-SR04 has 4 pins and these functions are carried out separately. If I were to jon these two pins, would it still function in the same way?
Have a look at this:
