TinyDuino Processors & TinyShields / Re: USB TinyShield and Bluetooth

Is the baud rate in the program .ino and the Serial Monitor the same?

Hello Tommy,

The Tiny Arcade is actually modeled around the hardware of the TinyScreen+, so you should be able to upload the program from the TinyScreen+ Video Player tutorial to your Tiny Arcade just fine. This tutorial includes a program that lets the Tiny Arcade simply play the videos on the microSD card when powered on, without a menu.

If you want to get your Tiny Arcade back to having the menu for games and videos, follow this tutorial: Then you would be able to play the games with the menu choice, as well as have an option to play videos alongside the games on the SD card.

The length/file size of videos loaded onto the SD card are limited by the size of the microSD card you have.

You don't need to use boot mode each time you upload a program, only if the board seems unresponsive to programs or the port is not showing up when you go to program it.

Thanks for the renewed interest! We hope the addition to your daughter's dollhouse looks great!

Hey vpete,

I'm looking through the program, and I'm trying to match what step you're stuck on. It looks like when I have the WiFi info in, but the Cayenne information filled with nothing, it stops the whole program for some reason. I tried putting a delay, but now I have the green light for connection and a blinking yellow light.

Do you have your Cayenne authentication entered? If not, I would recommend commenting out the
Code: [Select]
Cayenne.begin(username, password, clientID);
line to focus on just getting the WiFi working. It may even help to comment out
Code: [Select]
Cayenne.loop();in loop() and effectively removing all Cayenne shenanigans.

I didn't hit the endless "..." loop like you did, so I'm curious what your program looks like. If you've made some changes, it would help for you to post your code so I can see what may be going on (minus your WiFi information of course)

I'm not aware of a system check for the WiFi board at the moment, but I will look into it!

Hello vpete,

It may just be that you're not getting a strong enough connection. If you are using a laptop and are able, I would advise moving closer to your Router.

It also never hurts to double check the input network information is correct at the top of the program.

Hello nobsy,

I have successfully been able to program a TinyDuino on MacOS Sierra for a couple of different projects, so I'm not sure what issue you may be encountering as the Port seems to show up for the Yosemite OS and not Sierra.

I'll first advise you to ensure the power switch on is toggled to 'on.'

If that's not the issue, you may want to check out the latter part of this tutorial to first see if your laptop is even recognizing the USB port:

This will quickly show you how to identify whether your Mac is identifying the TinyDuino connected via USB or not, removing the Arduino IDE from the equation.

If you're still having issues, we will look further into this, so please let me know!

Hello littlejohn,

A common issue with micro USB cables that many hobbyists encounter is that not every cable can transmit data. Many cables only transfer power, so it may be that the first two cables you tried are charge-only and that's why you unable to program the TinyScreen+ at first.

Whatever the issue was, I'm glad you were able to resolve it!

Hello donde,

Yes, you can use your previously bought boards with anymore you purchase from us with the tan, 32-pin connector. There may be some limitations with how many you can stack together, but it sounds like you just want to reuse the boards you already own to build something else, which is possible, and we encourage!

You can definitely reuse the TinyDuino and USB Adapter board for the WiFi project, you just have to reprogram them. This tutorial includes the program and some instructions to help you out with that:


TinyDuino Processors & TinyShields / Re: baud-rate issues...
« on: September 06, 2018, 10:25:02 AM »
To answer your question, it's possible both hardware and software can cause garbage printing issues. The common software issue, as you saw, is the mismatch of baud rates between two communicating devices. The different rates of communication essentially become foreign languages as the data is receiving and transmitting independently and there is chaos, which gives us garbage.
A common hardware issue can occur when trying to communicate with more than two serial devices on one serial bus. When two devices communicate back and forth on one line, there is some order. When there are multiple devices communicating on one line, there is chaos, all devices could be speaking at once or none at all, again producing visual garbage on the Serial Monitor.

Does your second comment mean that the motors are successfully running? What kind of motors are you using?

Looks like a pretty fun project!

How are you loading the map? Are you using bluetooth, WiFi, or GPS?


I'll start by saying we're not quite sure how to answer that, but I can show you the specs of the TinyArcade and some old gaming platforms so you can make your own conclusions (that I hope you'll share)

Arduino Zero Processor

32 Bit Atmel ATSAMD21G18A ARM at 48MHz, DMA, USB
256KB Flash, 32KB SRAM
10-bit DAC, 12-bit ADC
Preloaded with Arduino compatible Bootloader
OLED display

96x64 OLED display, 16-bit color depth
0.96" (24.4mm) viewable area
Software controllable backlight (OLED brightness)

Built in Lithium Battery Charger, charges when USB is plugged in
Power Slide Switch
Built in voltage regulators - support external voltage input up to 5.5V

And here's a link for some old gaming platforms to compare to:

Let us know what you think!

It looks like you're missing some files or definitions, and you have duplicated data. The organization of your header files and libraries is probably in error.

I suggest looking up what these error messages mean so that you can begin fixing them.
For example, here are some forums that have solved some of your types of errors:
Redefinition errors:
Does not name a type error:

Can you copy the error messages you are getting?

Thank you

Hello DimSim,

There are plenty of arduino tutorials available online that will help you program this school project. Otherwise, you can bring more specific questions to the forum so we can help you along the way.

I'm glad everything's working now!
