MMM-Swipe - Hand gestures

Your left sensor

Vcc goes to pin #2
Gnd goes to pin #6
Trig goes to physical pin #26 (Which is labeled GPIO 23)
Echo goes to physical pin #18 (Which is labeled GPIO 24)

Your right sensor

Vcc goes to pin #4
Gnd goes to pin #9
Trig goes to physical pin #22 (Which is labeled GPIO 25)
Echo goes to physical pin #37 (Which is labeled GPIO 26)

You need both sensors if you want to detect movement.

@mochman OK, I’m an idiot!

I only have one sensor! Ha

Thanks very much for your help, I’m gonna get one ordered then get back on it.

Sorry for the daft questions

mochman

No worries. Yeah the sensor looks like it has 2 detectors on it. I’m pretty sure one is the speaker and the other is the microphone detector.

@mochman when I use your workaround i get the following errormessage and a whitescreen:

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?

Launching application.

Can you make another config.js file with just the MMM-Swipe module in there? I don’t know what the:
WARNING! Could not load config file. Starting with default configuration. Error found: Error: Module version mismatch. Expected 49, got 48. means.

BeLuGe

@mochman I change the config file to default and add your Module. The same errormessage.

mochman

@BeLuGe Try running rm -rf node_modules/ inside the MMM-Swipe folder then running npm install again.

BeLuGe

@mochman I have delete the directory and install the packages with npm install
And I have reinstall the complete Raspberry and install only your module.
The error is still there

mochman

I can’t help you then. That was my last option. I don’t receive that error nor do I know what that error means.

@mochman and @BeLuGe can you tell us what are the versions you are using :
Raspbian Jessie or Wheezy, which version of nodes, npm … ?
From where are you running npm start (local, ssh) using sudo or not ?
I have the same issue as @BeLuGe and I would like to debug/understand what’s is the problem.
I already red it could be a nodejs version issue (compiling vs running version)
So guys tell us what are your configuration

Here is mine :
Rpi 3 updated firmware with rpi-update
Raspbian Jessie last version (apt-get update && upgrade && dist-upgrade)
Nodejs last version 6.5.0 ARM version (not sure if it’s 64 bit or 32 bit) from https://nodejs.org
Then install of MM and packages
MM is working fine until I add MMM-Swipe module configuration then got same error message about
Error: Module version mismatch. Expected 49, got 48.

Hope we will find the solution …
