That is not an entrance if anything it is an exit.
you're right, sorry for referring me wrong xD
redundancies of Brazilian Portuguese xD
I meant output, I'm not seeing any changes in output xD
I don’t think you are getting any signal into your analogue input, measure on the input pin of the Arduino with an oscilloscope to see. But then I don’t suppose you have one.
the only oscilloscope that would have access would be in class, but we are in quarantine :S
I notice on your proto board that you do not have jumpers on your red and blue power bus lines.
The gap indicates that there is a break in the bus.
Have you a DMM to check your circuit voltages.
well, the protoboard has many other things connected kkkk (rgb to test the desired effect, hc05 for control through an app)
but, it is energized yes, there is a jumper that did not appear in the photo but it is more to the right of the image that is connected to the blue bus on the other side of the protoboard, which is the one that is directly connected to the gnd, but by way of conscience I will connect directly to gnd, just to test xD
or would i have to connect anything else to the positive in this scheme? because in fact there’s nothing there, so there’s no load on the blue bus
