[SOLVED] "Error" when running Ultrasonic_And_Relay.py

Hi,
So I’m trying to follow the tutorial that the GrovePi Kit came with and I tried running the ultrasonic and relay code.

However, when I ran it, it just showed “Error” repeatedly down my terminal.

My ultrasonic sensor also gets REALLY warm after a few seconds when running the code.
Is there a bug with the code or is my ultrasonic ranger faulty?

Hi @amanda.anicete,

It might be that you don’t have the firmware flashed to your GrovePi. Do the following things in a terminal:

cd /home/pi/Dexter/GrovePi/Firmware
bash firmware_update.sh

This will flash the firmware onto your GrovePi.

After you do this, please give this script another go and see if it works.

Thank you!
