I´m new to Arduino, currently following the Starter Kit book - project 10.
The project does not work as expected - basically nothing happens. I checked the code and the circuit and they are correct. I also tested the motor by connecting it to the battery and it is functional.
When finishing project 9 I didn´t remove the battery and started building the circuit for project 10 right away, with the battery attached to the circuit. Could that have damaged the H-bridge? Is there a way to check that? (if so, how?)
Thanks in advance.
Could that have damaged the H-bridge?
Yes any partial powering of a circuit is bad, depending on what wires were connected when.
Always disconnect ALL power when wiring up anything.
Is there a way to check that? (if so, how?)
Only by trying to use it.
I had exactly the same problem just now with this project.
The problem is the shoddy breadboard that comes in this kit! I had a smaller breadboard that I bought separately and wired the H-Bridge up on that after the circuit failed to work, and it worked fine there.
I did try debugging the issue on the kit's breadboard but after a while I started to think the breadboard itself was the problem and I was proved correct.
