Hi Folks!
At this moment I am working on a new version of my instrument Knurl, which has 4 DC motors that compose a hurdy-gurdy system around a cello format. You can check the whole prototypes and iterations here: https://www.knurl-lab.in/
This is my first time working with motors on bela so forgive me my chance or errors 😛
I am following this tutorial: https://blog.bela.io/2018/12/10/bela-controlling-dc-motors/
Aware of this data sheet: https://www.onsemi.com/pdf/datasheet/tip31a-d.pdf
And I am using the components recommended in the blog.
I am running the same code from the blog from Robert: https://github.com/roberthjack/dc-motors-pwm (at this stage, I am not running yet new code)
I checked all the cables and connections
However, after 3 days trying I didn't succeed yet with it. I tried the 3 different possibilities (with or without an external power supply or the barrel jack pin)
I wonder if someone could have a look into this picture and check if I am missing something .
Thanks in advance!
