It was exactly the same version of the motor but at 5 V, a 28BYJ-48 with ULN included https://www.amazon.de/gp/product/B00DGN ... UTF8&psc=1
. I simply changed to a 12 V to have more torque https://www.amazon.de/gp/product/B07W65 ... UTF8&psc=1
Before burning something, this is the connections that I prepared:
This is the triple connection, the arrow shows TOWARDS THE BATTERY
this is the connection on the ULN2003 board (and I mean controller not the transistor
and this is the third part of the connection, fixed on physical PIN 6.
If everything checks, then I'll try out. By the way, how would I know if the 12 V motor is still good? The ULN2003 is still functional since it moves the 5 V version; what if the 12 V does not move? is there a way to check if it is still functional?
