Raspberry pi project

Question

Hi guys, I have a problem and I hope someone is willing to help me. I want to do a fun project with my raspberry pi zero. I want to do a portable mini ''console''. I have almost everything I need except the case (because I dont have a 3D Printer) and I want to ad to this ''console'' my own Controller. It's pretty easy. 4 buttons, 2 triggers, 1 Dpad and a Joystick. But I have 0 experience with diy Controller and that kind of stuff and I would need help. Is there a board that can signals from buttons and transform it into a USB signal or can I put tha signals direct in the Raspberry pi ( sorry if its not grammatical correct what I wrote) . I would really apreciate every help I can get.

They are different sizes. I used one of these https://www.amazon.com/gp/product/B012FOV17O/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 Which is quite small. Mike

It might've been worth having a search on the forums before posting this question. The following article might be a good starting point: PIK3A: The Raspberry Pi 3 IKEA Retro Gaming Table Paul

You may be interested in this U-HID board:

However the likes of the Arduino Leonardo is often used for this purpose as per the PIK3A project mentioned previously.

The ATmega32U4 microcontrollers have built in USB support so Arduinos using them offer this sort of functionality e.g.

Either should work fine for your needs.

You might also want to look at something like the TeensyLC. It should do keyboard emulation as well. Depending on where you are based it might work out a little cheaper too.

There is a guide to connecting the device together with some sample code:

There are some minor differences apart from size, however I don't think there is anything that will cause you problems.

Adafruit do some small ATmega32u4 based boards as well e.g.:

however if you are just starting out, then the Arduino Micro may be a safer bet.
