In my previous post, I explained how I have gotten interested in IOT devices lately. I recommend reading it before proceeding with this post as this is the first of a couple of posts that demonstrate how to put the IOT devices on a Raspberry Pi to good use. In this post specifically, I’ll show you how you can mount a Grove Base Hat onto a Raspberry Pi. The whole task should take you about 10 minutes in total.
Note: although I tested and run these sensors on a Raspberry Pi 3B+, they also work for the latest Raspberry Pi Model 4!
Mounting the Grove Base Hat
Mounting the Grove Base Hat is quick and easy. Here is what the package includes: 1 Grove Base Hat, 4 spacers, 8 screws.
You will need a cross-head screwdriver (size 0) for the screws.
The first task is to mount the spacers onto the Grove Base Hat. Just put 4 screws through the holes on each edge from the top down. Then use your fingers to screw on the spacers on each screw at the bottom of the Base Hat. Finally, use the screwdriver to tighten the screws while holding the spacers with your fingers.
Now that you have the spacers in place, you can place the Grove Base Hat onto the Raspberry Pi. The Base Hat fits perfectly onto the GPIO of the Raspberry Pi, you should have no issues putting the Base Hat straight on top of it. Make sure that you push down evenly on all four sides of the Base Hat to avoid damaging the Raspberry Pi GPIO or the Base Hat.
As the last step, you will have to screw the remaining 4 screws into the spacers from the bottom of the Raspberry Pi, tightening them gently with the screwdriver.
Congratulations, now you have your Grove Base Hat mounted on your Raspberry Pi. The next step is to install the grove.py software.
Installing the Seeed grove.py software
Once your Raspberry Pi is powered up and connected to the internet, you can now install the Seeed Studio provided grove.py software to make use of your Base Hat and attached devices. The installation is rather simple via one command:
curl -sL https://github.com/Seeed-Studio/grove.py/raw/master/install.sh | sudo bash -s -
This command will install quite a few additional packages and, depending on your Raspberry Pi and internet speed, may take several minutes to install.
