Several SRF05 sharing the same picaxe's trigger output pin?

Hi guys,

First of all, since this is my first topic here, I want to thank you all for this great community. I have learned a lot and I have just finished my first robot thanks to you :) I am now thinking about the next one, and here comes the question !

I'm afraid I'll be running out of outputs on a Picaxe 28X1. I plan to use 2 or 3 ultrasonic sensors SRF05 and I was wondering if it would be possible to share the µC trigger pin between them, since I'm reading them one at a time (I mean linking the 2 or 3 input trigger pins of the SRF05s directly to the same picaxe trigger output pin).

Thx :)

I think SRF05s could

I think SRF05s could “hear” each other’s echoes and get messed up if you trigger them simultaneously. This might depend on how you place them on your robot.

Thx !

I’ll check that !

And yeah, I will post my first robots very soon (I built 3 actually, but the first two ones don’t use µC).

Thx again :slight_smile:

Robots without

Robots without microcontrollers are still robots! Feel free to post 'em.
