TinyDuino / TinyZero voltage output
« Last post by acox1701 on October 12, 2020, 10:35:12 AM »
I was entirely unaware of the Ardueno Zero until I stumbled across the TinyZero, so any references to how the larger version works will not make any sense to me.

Does the TinyZero include a voltage pump, allowing me to plug a 3.7V lithium-ion battery in, and pull 5V from the 5V pin, or will I need an external voltage pump?

Alternatively, can anyone tell me where to find a higher voltage LI battery?

Appreciate any help.

TinyDuino / Re: Using multiple 9AXIS IMU TinyShield
« Last post by polar96 on October 12, 2020, 03:32:38 AM »
Hi, I am also working on a similar project to the second idea. The purpose is to monitor the motion of different body parts during exercise.

I have already purchased the individual components (1 Tinyzero board + 9 axis IMU shield + Bluetooth Low Energy TinyShield) and assembled 4 sets to be used on 4 different body parts concurrently. Are there any codes to program them to be connected concurrently to the android app and sync data in real time to the app.

Alternatively, is it possible to do a master and slave system, where one of the device is the master and the other devices are slaves. The master receives the sensor data from the other slave devices and sends it to the app in real time.

Are there any resources for this? Need help with the coding

Thanks!

TinyDuino / Re: TinyScreen Smart Watch Compiler issues

I finally had some success in getting the screen to display the time and work correctly but now I seem to having trouble pairing the watch to my phone via bluetooth. The app cannot seem to locate the watch when I scan for it. I'm able to locate the watch. It shows up as a BlueNRG and asks for a PIN before I can pair the phone to the watch.

Does the kit come with ribbon cables to connect each module or What? I got only the modules. However I got a coin cell battery holder but it wont fit in the stack. I ordered the battery also but what module does it hook to?  How does it power up? Any help out there? Liveone1232003@yahoo.com is my email.

TinyDuino / Re: read the status led for the battery

I believe I may have personally emailed you, but I will post the answers to your questions here for all forum users to see.

It depends on the processor board.

For the TinyZero – there isn’t a way to read the status due to the charging LED being encapsulated in a circuit with the voltage regulator.

For the TinyDuino – you would need to read the voltage of the processor and determine from there whether it is charging or not.

The TinyScreen+ is similar to the TinyDuino, and we have a ready-made tutorial for the TinyScreen+ and how to display the battery voltage if you are interested in knowing the state of charge of a TinyScreen+: https://learn.tinycircuits.com/Help/TinyScreenPlus-Battery-Voltage-Tutorial/ Just note that this tutorial only works for the TinyScreen+.

TinyDuino / read the status led for the battery
« Last post by varotodfc on October 06, 2020, 08:33:01 PM »
Hi everyone,

I wonder if there is a command to access the status of the led that indicates if the battery is charging or not and what is the name of that LED. 

For example:

Code: [Select]
digitalRead(LED_name)

John,

We do have 2-pin JST cables that you could solder onto a motor to use with the Dual Motor TinyShield: https://tinycircuits.com/collections/cables-connectors/products/jst-sh-2-pin-connector

We also have 3-pin JST cables for servos if you were interested in those as well: https://tinycircuits.com/collections/cables-connectors/products/3-pin-jst-sh-pigtail-100mm

Hope that helps!

Rena,

Thanks for the fix!

Question....do mating connectors with wires exist so that one can connect (plug in) a DC motor to the board (and solder the wire ends to the motor_?

John,

It looks like some recent updates went wrong on this page. I will fix them up today.

Thanks for the catch and letting us know!
