Hallo, ich will bei meinem Löwen Dart (Royal Dart) pydart spielen =) Habe jetzt alles gekauft was ich brauche..... Wie ist der Anschluss ans Board von Arduino ???? Wie muss ich die Matrix verbinden??? Vielleicht hat jemand sogar Bilder.... Vielen Dank

The wiki is not always available, when running has essential info.
I installed and connected my 4x16 for the first time last week. I connected the 4 pins to arduino A0-A3. The 16 remaining pins are connected to A4-A6 and 1-14. There are example arduino files in the download. The example file will need to be modified to use the appropriate pins as input and output, will post my arduino file in a bit.
Unfortunatly I ran into an issue completing the initial calibration of pydarts. I ha e not had time to bebug but i suspect it is because of the uniqness of pin 13.:
NOTE: Digital pin 13 is harder to use as a digital input than the other digital pins because it has an LED and resistor attached to it that's soldered to the board on most boards. If you enable its internal 20k pull-up resistor, it will hang at around 1.7V instead of the expected 5V because the onboard LED and series resistor pull the voltage level down, meaning it always returns LOW. If you must use pin 13 as a digital input, set its pinMode() to INPUT and use an external pull down resistor.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Found a typo in my statement above, should read A4-A5 and 0-13.
Also to not the special note for pin 13 has not been an issues. However I am having trouble with pin 0 &1.

Found a new issue with interfacing 4x16 matrix to an Arduino UNO. Digital output pins 0 & 1 can not be uses when the Serial/USB interface are being used, yes it is used to communicate with the PS or Pi... Currently researching other options to allow multiplexing pins.

Hi Mike !
Sorry the wiki is currently not available because it is self hosted and I work in my house at the moment. It will be back in the next few days.
Good luck !
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Posting my working Arduion code, modified version of the sample 4x16 matrix utilizing an Arduino MEGA 2560 rev3. With the 4/16 matrix 20 pins are needed & the Arduino Uno limits you to 18 pins for I/O. Thre are MUX shields that could be added to expand pins or potentially Charlieplexing, https://en.wikipedia.org/wiki/Charlieplexing. Howver the Microcenter has the Inland arduino 2560 for $10 so it was not worth the effort.
This config does not include the extra buttons for game control, that is future. Hope it is useful for someone.:

Your welcome. However, I can not claim the code as mine. This code was written by someone with more experiance than me. I modified it to fit my board. I'm stillworking it out but I beleive there is a way to get more i/o optioms from the arduino uno without adding hardware, will post a diagram and code once proven.

Agreed. WOuld you mind sharing your Arduino config?
The nano has more usable ports. Couple that with a Raspberry PI Zero W for one small package. Will require a little work to add sound if the monitor does not have integrated speakers. One could add a USB sound card & speakers.

OK ich dachte an den raspberry pi um das programm pydarts laufen zu lassen. Das problem beim raspberry pi ist, er benutzt ganze PIN Gruppen für andree Aufgaben, zum Beispiel Powermanagement.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I see your point in regards to using the pi for IO. Looking at the Nano as it is much smaller footprint that the Mega. I am interested in your connections to the Nano as analog pins 6 & 7may not be used as digital as well digital pins 1 & 2 are used for the USB.
Edit: I miscounted pins!!! Off to order a couple.

Hi !
Did you check the wiki ?
I recommand English since German language is not terminated yet.
You are welcome to improve it if something is wrong :)
Cheers !

Hello unfortunately I find nothing in the wiki. Have a 4x16 matrix and unfortunately do not know how to connect to the Arduino.
Cheers
