hello everyone
im having a problem in my code on how can use color sensor and IR sensor in a boolean if statement
your help will be greatfull

In the Arduino IDE, click on Edit, then Copy for Forum, that will copy your code.
Then come back here and just do a paste.

It sounds like a line 42 problem.

How is a color sensor to be used in a voting system? Would you not just want switches, and maybe a display?

6

i have the display screen in lcd but just the color sensor is the one failing me to connect that IR sensor to accept sustain color of ballot papers

Would you make a drawing (photo of pen and paper) of all the devices in your project, and post your sketch?

thats how it is

Thank you for posting the code, but please, use the <CODE> button to wrap your formatted code in a code block. See Post #7 for instructions.

11

what do you mean by that i donot get it

12

In your IDE, format your code using CTRL-T, then copy your code using CTRL-A (select all), CTRL-C (copy).

In your post #8, select all your code and delete it. Then follow post #7 or type ``` (three backticks) then paste your code, then ``` (three backticks). It should look like Post #7.

And, these are nowhere in your sketch.

Please correct your post and add code tags around your code.

There is a small pencil image below your existing posts.

  • click on this pencil ➜ that will let you edit your post.
  • Select the part of the text that corresponds to the code
  • Click on the <code/> icon in the toolbar to indicate that it is code
  • click image Save Edit

(Also make sure to properly indent the code in the IDE before copying and pasting it here. This can be done by pressing ctrlT on a PC or cmdT on a Mac)
