Hello,

You should be able to get around 2-5x the sound by pressing and installing the speaker more firmly. To do this, take off the white sticker and adhere the speaker firmly against a flat surface. It may help to have the Video Player on with a video playing and testing the audio while pressing on the speaker.

Otherwise, there is some volume control and settings that you can play with. The settings menu tutorial is here: https://learn.tinycircuits.com/Kits/TinyTV-Tutorial/

You may also want to try converting videos with higher volume, as the volume level at the time of conversion is the volume level you end up with.

Let me know if that helps!

Thanks,
Réna

TinyLily / Re: Programming the tinylily directly via avrdude
« on: April 20, 2021, 07:32:14 PM »
Hello,

This is the command that gets run by the Arduino IDE:
avrdude -v -patmega328p -carduino -PCOM1 -b57600 -D -Uflash:w:a.hex:i

You can test this by following this tutorial https://learn.tinycircuits.com/TinyLily/Processor_TinyLily_Tutorial/ and then going to File->Preferences in the Arduino IDE and checking the boxes for “Show verbose output during: compilation upload” in the window that pops up.

Hope that does the trick! Thanks!

TinyDuino / Re: How to attach external power switch?

Best of luck! I would also recommend a magnifying component, like a helping hand like this one: https://www.amazon.com/Neiko-01902-Adjustable-Magnifying-Alligator/dp/B000P42O3C/ref=asc_df_B000P42O3C/?tag=hyprod-20&linkCode=df0&hvadid=312096335436&hvpos=&hvnetw=g&hvrand=8060824884059595120&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9060445&hvtargid=pla-448870101576&psc=1

They are sold everywhere and there are many versions, so the above link is just a suggestion with a picture.

TinyDuino / Re: A0 works as analog input, but why doesn't A5 seem to?
« on: April 20, 2021, 12:29:45 PM »
Hello there,

A4 and A5 are also the pins used for I2C devices (A4-SDA, A5-SCL), which can normally be used as regular analog pins when no I2C devices are being interfaced, but the TinyZero has the option of an onboard accelerometer that relies on I2C. It is likely you have an accelerometer populated on your board that is interfering with your ability to use pin A5 for regular analog. You can check this with the pictures on the product page that show where the small black chip is: https://tinycircuits.com/collections/processors/products/tinyzero-processor?variant=21137366515796

If you click between the Not Present and Present options, it should be clear where the part is.

Let me know if that seems to be the case!

Thanks,
Réna

Hello,

It is possible to hook up some wires to the TinyZero for a distant switch. To do so, however, you need some pretty careful/small soldering.

I attached an image of the power switch on the TinyZero with some pins colored. The two switches that you would need to solder to are red and yellow in the image, the other 5 pins of the power switch are all connected to ground and are boxed in black to show this. I also tossed in a reference to the schematic with the colors coordinated to offer some background explanation.

So, yes it is entirely possible, but you need to be careful when soldering pin 2 (yellow) because it is very close to a ground pin on the left. If you were to short, or solder, pin 2 to the nearby ground pin - things would blow up when powered and effectively ruin the board.

So tread carefully as you solder!

Thanks,
Réna

Hello there,

I'm sorry this post was sitting for so long - I missed it!

When a board works attached to USB and then doesn't work wirelessly, it is normally something program-wise in the setup() loop that involved Serial communication, or some logical error that prevents the program from continuing.

If you are still having the same problem - can you attach your code so I can take a look?

Thanks!

General Discussion / Re: DIY TinyTV Kit "card not found!" error
« on: March 31, 2021, 01:17:28 PM »
Hello,

The tutorial with the Arduino program, and the code that ships on the TinyTV kits is the same, so this tutorial shouldn't drastically change functionality if uploaded correctly (by selecting TinyScreen+ and the correct COM# in the Arduino IDE): https://learn.tinycircuits.com/Kits/Tiny-Video-Program/

If you loaded the Tiny Video Player program rather than the TinyTV kit program, you can change this in the settings menu once you solve the "Card not found" error: https://learn.tinycircuits.com/Kits/TinyTV-Tutorial/

It looks like you wrote in an email form as well with the same problem, but I will repeat myself here for anyone else having the same issue:
Often when this error comes up, the MicroSD and Audio TinyShield is not plugged into the TinyScreen+ board fully. Do not press with excessive force, but I recommend taking the sd card out, then taking the TinyShield out, and then trying to re-seat the board into the TinyScreen+ connector with even pressure. Test again before closing the TinyTV enclosure.

Best,
Réna

The error could come up for many reasons. You can try to post your reply in an incognito browser, or perhaps there was a symbol or other banned behavior that was included in the discussion post.

General Discussion / Re: open source TSV converter?
« on: March 29, 2021, 02:31:08 PM »
Hello,

There is a source python file for the TSV Converter. It is attached. It was not previously posted on GitHub since the Windows and Mac apps are all that most people need, but I will make sure it gets added. All of our software is open-source of course, we just missed getting this posted somewhere. 

You should be able to run the python file (dependent on python 2), but do not use the system theme, and you will need to have a copy of FFmpeg to get it working properly. The TSVConverter is mostly a UI wrapper for FFmpeg.

A .tsv file can be an mp4, gif, or converted image

Hope that helps!

If you wanted the fade effect to move faster, you can decrease the delay. It looks like you have it at 50ms in your program.

Can you verify you are using the exact Arduino example for pin 9 that I included above?

The program you included before differed from the Arduino example so I am unable to help you further without knowing what complete code you are using.

To clarify, the loop() in the Arduino program loops over and over on the TinyDuino, so the first line of the code snippet you included " int brightness = 0; " initializes and sets the brightness variable to zero on every loop iteration. This is likely the problem. The brightness variable, as shown in the Arduino example I included, needs to be a global variable outside of the loop() function in order to be usable between loop iterations.

The messy wiring on the ground pin could be shorting the gnd to a voltage pin right next to it. What LED are you using?

Quote
ALL of the LED's work independently,

Are you saying all of your LEDs have been tested and work with the pins you are programming?

Quote
I tried pins 3, 5, 6, and 9 - and none had any effect.

Does this mean that you edited and uploaded the program for each pin as you changed your hardware configuration? Are you uploading to the correct TinyDuino pin? Do you get a "Done uploading." message each time you upload the program?

Send a picture of your hardware layout to verify the correct pin connections. I tested the example from Arduino and was able to get the fading behavior, picture attached of pin connections using jumper cables and pin 9.

You said that pins IO3, IO5, IO6, IO9, SS (IO10), MOSI (IO11) are PWM; I'm assuming you're referring to the pins marked 3, 5, 6, 9, SS  and MOSI; I have the LED connected to pin 9, but it does NOT do anything at all.

You typed pin 9 in your recent comment.

Is your LED facing the correct direction? I recommend trying the exact program and pin layout from the Arduino tutorial before making any edits or trying other pins so that you can make sure you are using a working program and working layout.
