What does this mean; does not name a TYPE

Projects Programming
1

I keep getting this error message: TestDCMotorDriver:18: error: 'MeDCMotor' does not name a type

Every variable has to have a type. The type you have in front of a variable name is not a type that the compiler recognizes.

Without seeing your code, that is all the help you are going to get. It does look, though, like you have failed to download a library, or have not installed it correctly.

If the motor you are saying refers to a number it should have a type such as int or double, for example. This declares its type.

OK ... Thanks in advance.
I'm trying to get the Makeblock starter Tank up and running.
Here is the code, what do I need to in order name a TYPE? and where does it go in the code block?

Did you download this library? From where? Where did you install it?

You don't need to modify the code. There are some problem in the library. You can download it here https://github.com/Makeblock-official/Makeblock-Library

Hi Trex_5
I downloaded it from your link and installed per the instructions, but i still get the 'MeDCMotor' does not name a type.
Anyway of unloading the MakeBlock.h and reinstalling in Arduino IDE?

Any suggestions appreciated

Thanx

The complete library should come in a folder that you copy to, inside your Arduino folder,

Software->arduino-version number->libraries.

You should be able, in the IDE to click the Sketch pulldown up top and choose Import Library and get it.
If it's not there then you did something wrong.

If the library has Examples then you should be able to load any of those through File->Examples->library name->choose one.

GoForSmoke:
Software->arduino-version number->libraries.

In Windows it would be ...\Arduino\libraries, where ...\Arduino is the directory where your sketches are stored.

I'm running XP and know how to browse my own folders, thank you. Must be my install. I have 0022 and 1.03 folders in the Software folder that is in the Arduino folder.
