Make sure you indented the code in the IDE, that's done by pressing ctrlT on a PC or cmdT on a Mac)

You'll see that you have an wrongly placed closing } in the loop (line 90), which makes some of the code fall out any function.

if you fix this you'll still have other challenges, make sur all your else are attached to an if and that () and {} are balanced

You can only have one 'else' per 'if'. You can have multiple 'elseif's but only one 'else'. Not too sure of your logic, maybe you needed nested if/else statements to achieve what you were going for?

johnwasser · February 22, 2022, 3:26pm

You can't have an 'else {} else {}'. You can only put an 'else' on an 'if': 'if () {} else {}'

J-M-L · February 22, 2022, 3:28pm

yes, as I said above

randy_serv · February 22, 2022, 3:45pm

how about this one?

Arduino: 1.8.19 (Windows 10), Board: "Arduino Mega or Mega 2560, ATmega2560 (Mega 2560)"

Sketch uses 26944 bytes (10%) of program storage space. Maximum is 253952 bytes.

Global variables use 622 bytes (7%) of dynamic memory, leaving 7570 bytes for local variables. Maximum is 8192 bytes.

J-M-L · February 22, 2022, 3:53pm

initially you were compiling for a UNO and now for a MEGA....

which board do you have?

randy_serv · February 22, 2022, 3:59pm

mega 2560 sir

J-M-L · February 22, 2022, 4:02pm

did you check the common issues?

randy_serv · February 22, 2022, 4:05pm

yes sir. i already checked

J-M-L · February 22, 2022, 4:09pm

what did the loopback test show?

alto777 · February 22, 2022, 4:13pm

Did you

Check that your USB cable is working. Test it with a different device, or try using a different USB cable. Make sure it is a data cable, a charge-only cable will not work.

Or a different USB gazinta, or with or without a hub &c.

Also not mentioned or I didn't see it is to reboot your machine.

It's probably the only reason I ever have to… I can go weeks with no trouble, other times right away but sometimes my USB ports become, one by one, locked out unavailable.

I have found no other way to force the USB subsystem to reset itself.
