General Discussion / Re: Making the cap touch board more sensitive for touchless commands

« on: November 10, 2022, 10:32:40 AM »

Have you tested the 1/2" silicone with the cap touch sensor?

If you want to edit the library, the CapTouchWireling.h and .cpp are available on our GitHub: https://github.com/TinyCircuits/TinyCircuits-ATtiny841-Library

You should have a local copy of the library from the tutorial example.

Cheers,

Hi there,

Since silicone is an insulator, you would want to extend the touch points/copper plates. I'm not sure on the exact material specs involved that might answer how much copper, but something analog (like a push button) might work better than scraping the insulation on the PCB and adding more copper.

Can you tell me more about what you are making? I may have some better recommendations on how you can accomplish your goals.

I'll add that I've applied a 1/8" sheet of acrylic to the cap touch pads directly with some double-sided tape and had luck with being able to detect a touch. Have you tested the silicone layer? Can you do a thinner layer? What all have you tested so far?

Cheers,

TinyTV & Tiny Video Player / Re: Create timer

« on: November 04, 2022, 10:59:17 AM »

Hi there, welcome to the forum!

It is possible to use the RTC on the SAMD21 processor that the TinyTV is built around, but I wouldn't categorize this as a beginner's project. If you would like to take a look at the code for the RTC alarm setting and the TinyTV program you would embed this in, here are some links:
TinyScreen+ getting started: https://learn.tinycircuits.com/Processors/TinyScreen%2B_Setup_Tutorial/
RTC:  https://learn.tinycircuits.com/Help/TinyScreenPlus-RTC-Interrupts-Sleep-Mode/
TinyTV program: https://learn.tinycircuits.com/Kits/Tiny-Video-Program/

A faster/easier way would be to get a smart plug that you could set to turn on for the few minutes a day that you'd like, and then leave the TinyTV plugged in and on so that whenever the plug powers the TV, the TV is on and playing videos.

Let me know if you need any clarification or if you have any other questions!

Cheers,
Réna

Wirelings / Re: LRA Wireling Power Issue

« on: November 03, 2022, 12:26:01 PM »

With nothing in your loop(), the hardware has nothing to repeat or continue doing after the setup() loop runs. I'm not particularly familiar with the audio to vibrate mode you are using, but I assume you need to read the audio data and process it with the library repeatedly like you might do with the loop() logic.

You can try calling your setup() loop in the loop() to see if re-writing to those registers does what you need, but you might need to add something else for what you are trying to accomplish:

loop() {
     setup();
}

Hello,

There could be some serial communication or setup code that could be interfering. Can you share the code you are working with to rule that out?

TinyTV & Tiny Video Player / Re: no sound after video conversion

« on: November 01, 2022, 02:07:36 PM »

Hello,

The TinyTV Converter App does not convert audio for .tsv files yet, to convert videos with audio you will need to use the TSV Converter found here: https://learn.tinycircuits.com/Kits/TSV-Converter-Tutorial/

TinyTV & Tiny Video Player / Re: Tiny TV Kit Flip Video ?

« on: October 17, 2022, 02:45:11 PM »

You could flip the screen in the code, but flipping the video would probably be easiest since there's no programming involved!

Let me know if you need other options or ideas for accomplishing your project. Would LOVE to see it once you have it built the way you want it!

TinyTV & Tiny Video Player / Re: What formatting is required for the video files?

« on: October 03, 2022, 12:28:16 PM »

Hello!

There's a bug in the newest TinyTV App so it's not currently converting the audio streams properly of the custom .tsv videos.

Until there's a fix for the TinyTV App, use the TSV Converter app here: https://learn.tinycircuits.com/Kits/TSV-Converter-Tutorial/

Wirelings / Re: Output Differs using Wireling Analog than ProtoTermimalShield on TinyZero?

« on: September 21, 2022, 03:07:56 PM »

Linda,

You should be able to leave out the #include <Wire.h> line and you won't need to select the ports since you just need to interface with the pin.

As long as no errors come up with those revisions and everything is working as expected, all should be well!

Hi there,

Thanks for posting your example code and detailing your process so well!

It looks like you need to add Wireling.begin(); to your setup loop. This function is needed for all Wireling programs to put the power pin of the Wireling TinyShield and other Wilreling boards in the correct mode.

Let me know if you have any other questions!

Cheers,

TinyDuino Processors & TinyShields / Re: Dual Motor Shield - Make the link between the PWM value and the actual voltage

« on: August 22, 2022, 06:28:32 PM »

Hi there,

There are lots of resources to learn more about PWM. You can start here: https://www.arduino.cc/en/Tutorial/Foundations/PWM

As for the voltage output, you can measure this directly using a voltmeter.

I hope that helps!

General Discussion / Re: A newbie asking for Help for a custom Inclinometer project :)

« on: August 22, 2022, 11:47:29 AM »

Hi there,

The Tiny Inclinometer project could work with the use of a ribbon cable TinyShield to distance the display shield by 6 inches - unfortunately, the ribbon cable TinyShield would still need to be attached to the display and would make that section of the project two boards thick. The ribbon cable: https://tinycircuits.com/collections/cables-connectors/products/tinyshield-ribbon-cable-extender

The TinySaber board has an accelerometer built-in, so it sounds like that would be the best option for your project guidelines. You can buy the kit and use just the board for your application if that works best for you. Here's a programming tutorial: https://learn.tinycircuits.com/Kits/TinySaber_Programming_Tutorial/

I hope that helps.

Cheers,

« on: August 16, 2022, 11:31:27 AM »

Hello,

It seems like there is a bad connection. It doesn't happen often, but it's possible that some of the pins on the tan connectors could be bent from assembly at an angle. Are you able to inspect the pins on the connectors of the SD & Audio Shield and the TinyScreen+ and see any issues? If there are no issues, I do recommend a reassembly - don't forget to add the bracket pieces inside the TV to keep the two boards together.

If that doesn't work, you can try taking all the hardware outside of the TV to see if you can note any fitting difficulties or if it works outside of the case. It's possible the tolerance of thickness of the TV print is preventing a good connection between the two boards.

Let me know how it goes.

Cheers,
Réna
