Glad you were able to figure it out so fast!

Solved... use the SerialMonitorMacro:
#if defined(ARDUINO_ARCH_SAMD)
#define SerialMonitorInterface SerialUSB
#define SerialMonitorInterface Serial

 * Set up the IO and serial port
void setup() {

I checked the code with the serial port shield and the tinyZero: It works but I have to switch the USB cable between the CPU board USB and the serial shield USB. That is a pain :(
TinyDuino / TinyZero Serial Port Communication
« Last post by temecom on January 27, 2020, 11:38:38 PM »
I just received a tinyZero and went to run a serial port test program that runs on the regular tiny with the serial shield... Nothing. I can't get a character on the port monitor at any baud rate. Can the onboard port be used for Serial communication or do I need to still use a serial port shield?

Simple serial test (LED flashes OK:

#include <ArduinoJson.h>
#include <Ethernet.h>
#include <SPI.h>
#include "tinyGarageDoor.h"

void setup() {
   // Initialize Serial port
  while (!Serial) continue;
  Serial.print(F("Tiny-Garage Version: "));
  // initialize digital pin LED_BUILTIN as an output.

void loop() {
  Serial.println("Checking door... ");
 digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW

I hope this other informative comment from mjculross has helped you with the "No SD Card Found error" but if not, let me know if you are still encountering problems and we will try to resolve it! It may indeed be the SD Card having issues after so many years. For future reference, the TinyCircuits email for help is Please let us know where you found an incorrect/dead email so we can make sure that doesn't happen to anyone else!

If I remember correctly, the TinyArcade will allow you to play the last game loaded, even without the SD card installed (you should be able to verify this by powering down, completely removing the card, & powering back up).  As for reprogramming the board (you should not have to, but doing so can be instructional), make sure you follow all of the steps given at, particularly the setup steps at  Once you've included the URL in the "Additional Boards Manager URLs" box in the IDE Preferences, and installed the "Arduino SAMD Boards (32-bits ARM Cortex-M0+)" & "TinyCircuits SAMD Boards" choices using the Boards Manager as indicated in the instructions, then the "TinyScreen+" should be available for you to select under Tools->Board in the IDE.

You should also try simply reseating the microSD card several times in case minor corrosion has formed on the interface between the microSD card & the socket.

Hope that helps . . .
Tiny Arcade / Issue with Micro SD card reading

Hello, I wanted to ask how I can fix a recent error that has started on my TinyArcade. I was an early backer for the Tiny Arcade, and since having it, it has worked without issue since. However lately, I get a problem where when I turn on the TinyArcade, it tells me no SD Card was found, yet it still brings up the “Tiny Shooter” game but that’s it. I did buy the pre-loaded card from your company and I checked and all the game files and the demo videos are on it, but the arcade still doesn’t see any of them. It is strange because even though it states “no SD card found” it still brings up the game I mentioned earlier. I tried to reconfigure the SD card and update it with all the new games, but it still doesn’t see any thing but the Tiny Shooter.
 I thought perhaps I needed to just reprogram the board via the Arduino IDE, but to do that I need the files for the TinyScreen. On your website you state that we need to copy the following URL and add it to the Board Manager so I could update the Board but this link doesn’t work in Arduino IDE. Is there a new link?
I also tried to email the company, but the email address is dead as well.
Tiny Arcade / Re: TinyScreen+ on/off switch broken... suggestions/?
« Last post by lennevia on January 22, 2020, 01:06:53 PM »
This is a lame idea, but I would suggest gluing the plastic part of the switch back on. Or if there is something else you can adhere to the broken end of the switch to make it more usable.

Thanks, that makes sense and I got it working. For any newbie like me following, I downloaded the code in the first link and unzipped. Maybe this is not the best option, because I got compile errors because header files couldn't be found. This was fixed by copying the TinierScreen and FastLED folders from the unzip location to the Arduino library folder (on MacOS it Documents/Arduino/libraries).

Hi Michael,

The code for this kit has been updated and is available for download here and can be viewed here. We came across a software issue related to the buzzer that would cause the program to freeze. This issue has been resolved and will be documented on the Learn page soon.

If you're not familiar with how to upload code to the WirelingZero, there are instructions available on our Learn site here.

Hope this helps.
