Recently purchased the GrovePi+ Starter kit. Not having much luck with the analog sensors.
I have connected the rotary angle sensor to analog port A2 and the green led to digital port D5. The supplied LED_fade.py program fails with “Error” being written to the screen repeatedly. I am running the script like this:
sudo python led_fade.py
I believe I a running the latest version of Raspbian for Robots (image file is 2016.05.09_Dexter_Industries_Jessie.img)
I have also tried the light sensor and sound sensor on analog ports A0 and A1. They also fail with the same symptom.
Hey rsmith,
Sorry for taking this long to reply. Looks like the Pi is unable to communicate with the GrovePi. Can you post a picture of the setup. Did the GrovePi work a few times or has it not worked at all.
