Wiring Ultrasonic Ranger Finder
 

We recieved the High Performance Ultrasonic Range Finder in the KOB, but we dont know how to wire this to our robot. Can anyone help us. Thank you
Kyle

The Maxbotix sensor actually has several outputs you can use, depending on what you feel like interfacing with. It has a pulse-width output, which can be connected to a digital input and sampled for time high (if you can make it work via interrupts, that works even better), a serial input/output for using TTL-level serial communication, and an analog output for connection to an analog input on the CRio. I've found that the analog output is a little noisy (especially inside a robot) and isn't terribly precise, but the pulse-width output is great, and the serial output gives options to set when the sensor fires, which is useful for not interfering with other teams' sensors. Which input technique are you most comfortable with?

i'm not in Kyle's team but i would greatly appreciate it if you could say how to wire it with the pwm signal wires

Re: Wiring Ultrasonic Ranger Finder
 

I am also interested in finding out how to wire the pin-out's to work with the PWM slots on the sidecar.

The basic is red to 5V, black to GND, and White to AN
This will be connected to the analog breakout.

Note
I haven't tested this out myself. This is just what I've come across from research

I have, and your statement is absolutely correct.


Kyle,
I've answered this in other threads, Search is your friend.

thank you both very much :)

Can this sensor be wired into the Sidecart?

Re: Wiring Ultrasonic Ranger Finder
 

It can. You can find detailed instructions for exactly how to do it in the LabVIEW FRC examples.

Boom. Analog wasn't too bad for us, we had a readout on our driver station LCD that gave us relatively consistent voltage readings. (EZ-1 model)
