I'm having difficulty with the Starter Project #9: Motorized Pinwheel, and I was looking for some guidance on how to make it work.
I have done the usual - checked the code, checked the connections - but it still would not turn on. I read through other forum posts, and I saw one suggestion on changing the 10 kilohm resistor for a 220 ohm; that didn't; work, but when I removed the resistor completely, it worked (woo hoo!). Granted, the motor ran on its own, and the switch did nothing, but, as a noob, it was good to see that at least the motor did work.
My code and setup are below. I appreciate any insights as to where I might investigate further, so I could get this working properly.
PS I also changed the code and input to "8" as another post had suggested, replaced the switch, and used a different 10 kilohm resistor - none of these made any difference.
I'm new so I'm assuming a DVM is a Digital VoltMeter; if I had one, what would I be checking for? Is the hypothesis there is something wrong with the connection points?
don't see anything obvious..
maybe button inserted wrong in breadboard??
if you don't have a meter to measure resistance or volts..
experiment first with button and motor..
Thanks - I tried rebuilding this in TinkerCad, and it worked. I used the exact same setup as what I had build, so it makes me think something is off on my board, or possibly one of the switches.
Thanks for the idea - I tried that out, and it didn't light up. To compare, I had build a simulation in TinkerCad, and that worked. Would this indicate, to you, that the issue is the switch?
I think it is a switch issue. I went through every one, and none of them worked, but when I replaced the switch with a connecting wire, it lit up.
I really jammed those buttons in, but I still couldn't get them to work. They used to work, but I must have fried them on a project (maybe the keyboard one), when I having trouble IDing the resistors.
Thanks very much for the help. 'Tis greatly appreciated!
