code with errors for motorcycle shifter

Projects Programming
1

hi Arduino community!
I am new to arduino and trying to learn code but its a very slow and confusing process. i have found a very useful video online of a guy who has programmed his Arduino to work as a motorcycle quick shift and shared his code for everyone to use. im trying to program his code onto my UNO R3 but dont understand how to fix all the errors that pop up after i try to verify it. can anyone take a look at the code and see if they can copy and paste and verify it and send me a copy to try. below is the website link to the code as its too large to post in here. thanks

When you encounter an error you'll see a button on the right side of the orange bar "Copy error messages". Click that button. Paste the error in a message here USING CODE TAGS (</> button on the toolbar).

That error and that code don't match up... ::slight_smile:

im not sure what to do from here then?

You need to either compile the code you posted the link to or else post the code you're compiling.

The error messages make it clear that you're compiling different code and we can't see that code so there's nothing we can do to help you.

LiquidCrystal_I2C.h: No such file or directory

Means you don't have that library or it's not where it should be. Goto manage libraries and make sure it's installed.

13

is there a specific folder that the arduino program stores libraries in? i downloaded a zip folder and extracted it called liquid crystal but im not sure if it needs to be in a specific place to show up in libraries? your help is much appreciated thanks all

14

Libraries are searched according to a path configured somewhere in the install files. Generally however, there are two specific locations, one for the system libraries that come with the IDE distribution and will be found in the install directory. The other, for user-installed libraries, is found in a sub-directory called libraries in your sketchbook directory which is typically ..\MyDocuments\Arduino

15

Instructions for installing Arduino libraries:

16

Looks like the libraries required for that code can be found here-

   * You will need those Libraries :
   * Liquidcrystal_I2C v1.2.1 : http://tiny.cc/libLcdI2C
   * Wire                     : http://tiny.cc/libWire

as stated in the notes in the beginning of the program.

Ive changed to an Arduino nano, tried to upload the code onto it and get this error message. any ideas?

There is an incompatibility issue with IDEs 1.8.5 and later and the old bootloader found on older nanos. When you pull down the Tools menu and go to Board to select Arduino Nano, the next item in the Tools menu is Processor. By default this comes up as ATmega328P which you recognise as the nano processor and so ignore it and go straight to Port. You need to go back to Processor and select ATmega328P (Old Bootloader).
