I have a newly installed pi3 with node.js 9.9.0 and npm 5.6.0. I created a groove directory and installed the node-grovepi package using:
npm install node-grovepi
I also ran the quick install command:
curl -kL dexterindustries.com/update_grovepi | bash
It seems to all be installed correctly, but I don’t quite get it working. When trying the analog light for instance, I keep getting the same value (~20.0), but it makes no difference if I cover the sensor or hold it up to the light. If I put the sensor on a different port I get different readings (~0.01). So it seems like it can read the sensor but are not getting the right values.
If I try the leds nothing happends, not even an error…
var led = new GrovePi.sensors.DigitalOutput(2);
board = new GrovePi.board({...});
led.turnOn();
Appreciate any help
