The Super Easy Pico Keyboard
Introduction: The Super Easy Pico Keyboard
This is the easiest Raspberry Pi Pico to Keyboard tutorial. You can make in easy visualized steps a functioning Macro keyboard, Password keyboard, or anything that you can do with a keyboard.
I am also the original author and have made this tutorial in Dutch for the Makersbase. I am Tomodesigns and I do cool stuff on my Youtube and also Instagram! I am a dutch student with a passion for making and teaching others.
This tutorial is well tested on an audience with a beginner knowledge of soldering and coding. So you can also do this!
You can make your button casing with my laser-cut wood file or 3dprint file. You will only have to follow the wood or 3dprint steps depending on your chosen method. If you have a Pico and a button you can also follow this tutorial without building the buttonholder.
Supplies
These are all the parts we need for this Instructables:
* Button: https://amzn.to/3HKzllj (Diameter of 7mm)
* Wire (Red and color of your choice):
* 4mm wood or 3dprint filament
* Micro USB cable
* Raspberry Pi Pico: https://amzn.to/3neec9Q
* Solder tin
Here are all the tools we're going to need for this Instructables:
* Soldering Iron https://amzn.to/39NkQk9
* Lasercutter or 3Dprinter (Or nothing if you don't want to make a case)
* Cable stripper: https://amzn.to/39KrTdh
Step 1: Preparation Gluing (Wood)
Before we start making the box that contains all your electronics, we first have to collect the right parts. These are:
* Wood glue
* Wooden box parts
The wooden box parts file is included. You can laser cut this part or go to step 3 for the 3dprinted box if you don't have a laser cutter.
Step 2: Gluing (wood)
As you can see in the video above, you can now glue the box together.
NB! Do not glue the lid on the box yet. 996
This must still be able to open to put in all the electronics.
Step 3: Download and Printing Parts (3D Printing)
Download these files from this link: https://www.printables.com/model/241877-pico-keyboard
You don't have to use any supports for this print and it is around 1,5 hours of printing.
Infill doesn't matter.
Step 4: Preparation Soldering
For soldering you need a number of things:
* The Pico
* A button
* Two wires (red and color of your choice)
* solder tin
And we need some tools:
* Cutting pliers
* Cable stripper
* Soldering iron
* Little helper
Step 5: Little Helper (Info)
This is the Little Helper. This handy tool has a magnifying glass and two little hands.
With these hands he can, for example, hold your Raspberry Pi Pico while soldering. So that everything is easily kept in one place. In the other hand, it can even hold the cables that you are going to attach to the Pico.
Here is a link to buy this handy tool!
Always use the Little Helper when you can when soldering!
Step 6: Cable Stripper
To solder cables to your Knop and Pico, you must first remove the casing from the cables. This is called stripping cables.
We do this to expose the part of the cable that conducts the current hole. You can recognize these conductive smaller cables by the silver/bronze color. We are going to solder these on the Pico and Button.
Strip both sides of both your cables.
Step 7: Pico Soldering
In this step, we are going to solder both cables to the Pico.
We do this by first putting some solder tin on the pico where we will connect the wires.
We are going to do this on pin 3.3V and GP10 (see image)
Step 8: Button Soldering
In this step, we will solder the cables that we soldered to the pico in the previous step to a button. You have 2 pins on the button. Solder one wire per terminal.
Make sure the ends of the wire do not touch!
Make sure you soldered everything to the right points!
Step 9: Attaching Button
Now we put the knob through the hole in the lid and tighten it with the nut!
