MMM-Swipe - Hand gestures

paviro

@mochman to use GPIOs without root try exporting them via a shell command within node. The user than only has to be part of the gpio-group‘ :) check my MMM-PIR-Sensor` for an example!

mochman

@paviro Does that only work with setting pins directly? I am using a helper_node that takes care of all of the pin setting and timing for the sensors. It looks like your code sets pins directly with the exec command. I’m not sure how to do that with the npm usonic functions.

@mochman I’m a complete amateur here mate

I’ve got this far, but no idea what to do next :(

Now what?

I didn’t understand in the readme what it meant by pins etc.

mochman

@Mitchfarino Looks almost all good. I’m not sure if you have your trigger pin hooked up to ground from this picture. The pins in the config are not the actual pin #'s of the header. It uses the GPIO#. I use this picture as a reference.
RP3 GPIO

As an example you can see that pin 32 is called GPIO12. If you connected your Trig wire to that and your Echo wire to GPIO16 (physical pin 36). In the config.js you would use :

echoLeftPin: 12,
triggerLeftPin: 16,

and then a similar setup for your other sensor.
If you are still having issues with the setup, please let me know.

As a reference point, your red wire is connected to physical pin #2.

@mochman I have a problem when installing the modules. When I enter the module in the config. When I start the Magic Mirror I get the following error message and a white screen.

@BeLuGe Have you run npm install in the MMM-Swipe folder? Are you running the mirror with sudo? If so would you mind posting your config.js file. Thanks.

BeLuGe

@mochman Yes I have run npm install in the MMM-Swipe folder. I running the mirror without sudo.

@mochman I’m only just back looking at this

Any tutorial I find online says I need a breadboard too - is that correct?

What pins should put these in? Or where can I find resource on how to do it?

mochman

@BeLuGe So I just tried this myself. When I created the module, I was connected to the pi to test. I just tried using SSH to start the program and got the same error you’re getting. Looks like it’s a issue with running a sudo command over SSH, the workaround I found was to run sudo cp ~/.Xauthority /root/ then run DISPLAY=:0 sudo npm start. The problem with this is that everytime you restart your mirror you will need to run the copy command again.

@Mitchfarino You don’t need a breadboard. I just used one to test out my configuration. You can hook it up directly to the pi using those wires you have already connected. When I tested out my setup, I used these pins.

echoLeftPin: 24,       
triggerLeftPin: 23,     
echoRightPin: 26,      
triggerRightPin: 25,

Remember that those are the GPIO #'s and not the physical pin #.

Mitchfarino

@mochman I have vcc, trig, echo and gnd on my sensor - how do they map to the config you have posted?
