Need help for uploading

[siya_uni_1]

Hi i am new to this, I am having a problem with my code or something, but when I upload my code in the Arduino Uno, it shows this error messsage:

Error compiling for board Arduino Uno.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

I know it is a problem in the code, because i tested it on two different arduino boards, and both work. I even selected correct board type and port.

Welcome to the forum

As your topic does not relate directly to the installation or operation of the IDE it has been moved to the Programming category of the forum

As to the error, you have

if (rs = HIGH && ls = HIGH && cs = HIGH){

Use = to assign a value to a variable
Use == to compare two values

You apparently did not read How to get the best out of this forum. If you did, you would have known to include the sketch that was causing the problem so we could see what you had done incorrectly.

I would imagine that you have tried to redefine HIGH and LOW somewhere in the sketch that you didn't show.

Take 2x 3 minutes of yout time to learn how to post code or error-messages as a code-section

Make experienced users help: two ways to quickly post code as a code-section

Hi newcomer, This thread wants to show you how you can speed-up getting helpful answers with small effort. If you manage at least to post this way. You have the sympathy of the experienced users. If you are willing to invest another 20 minutes these 20 minutes extra-time will save you a minimum of 200 minutes to finish your project. always post your full sketch. As a code-section from the very first to the very last line A code-section has a small height => keeps your posting "short" but e…

If you get a compiler-error or an upload-error provide all details for analysing the error

Hi newcomer, the Arduino-Forum community can be of great help. If the community is able to support you in a way that helps solving your problems depends on detailed information that you should provide. trying to be quick by posting a too short posting is just slowing down finding the solution. Because all that happends is that you are asked for the detailed information and have to provide it anyway. Only difference the answer and the solution comes later The most important thing is to post …

thanks. i forgot that in equals to under an if condition, we have to add two equals to symbols
