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.
