Grove Shield / Grove Starter Kit for Raspberry Pi Pico

This demo assumes that Micropython firmware is already installed on Raspberry Pi Pico. Instructions for installing this firmware are at https://projects.raspberrypi.org/en/projects/getting-started-with-the-pico/3

The link to lcd1602.py is dead. There is a simple micropython driver for the LCD display at github user Bhavithiran97's page, but using it requires recoding the demo.

Hi~ I just tested the demo on my side, and it works well. 👌
Could you double-check if you’ve downloaded correct ws2812.py files?
The link is here: https://files.seeedstudio.com/wiki/Grove-Temperature-Humidity-Sensor/ws2812.py 👈
And if possible, could you also share the steps you took so I can try to reproduce it exactly?

Hi, I nuked my Pico and downloaded the file again, Also copied and pasted the code from the WIKI and it worked. Now I know I’m new to this but I’m sure I did it correct the first time so I’m not sure what is going on. Thanks for your time in looking into this for me now onto the next part of the kit :-) Kind Regards Paul

For Project 6, I don't think the servo should be being run through 0 to 65535, but rather the 2.5% and 12.5% value of that range. It seems the servo is a 50Hz, 0 to 180 degree range where 2.5% is one end and 12.5% the other. The Servo specs dont really tell you much.

Why are there 2 version 1.0s with diffrent silk screens? The one I have has the version number on the other side.

Thanks for bringing this up!
Could you please share a photo of your board so we can better understand the version you have?

Just a note for Project 2: Detecting Temperature and Humidity and Option 2: DHT20 and LCD1602...

There seems to be an error in the steps:
The Grove Temperature & Humidity Sensor V2.0 (DHT20) has to be connected to I2C0, not D18.
Then I connect the DHT20 sensor to D18, it cannot be initialized.

Looks like a copy and paste error from option 1 ;-)

Thank you for your feedback! We’ll check and fix the issue right away.
