Hi, I am new to this forum and a beginner in working with Arduino Uno. I have an Arduino Uno R3, and so far, I have tried the basic LED blinking program. The first time, it worked correctly. However, when I changed the time delay in the code, it stopped responding and showed the error message: "exit status 1".
@tanjilahmad23 Welcome to the forum! Have you checked that the correct board is selected in the board selector at the top of the IDE?
Before posting your code and schematic, please review the forum guidelines and use code tags to ensure clarity. Additionally, include links to the technical information for your hardware and provide a preliminary schematic that shows all power, ground, and power sources.
For more guidance, please refer to this link:
Important Notes:
-
Breadboard diagrams (often referred to as "frizzes") are not considered proper schematics in this context.
-
Wiring diagrams are helpful for assembly but are not effective for debugging.
-
Screenshots are discouraged because they are often hard to read. Please provide text-based code and clear, high-quality images of schematics.
Providing the correct information will help others understand your setup and offer better assistance.
Just a tip on the third bullet point about screenshots, the way to provide error messages is, to first make sure that the cursor is sat in the output window and then in the IDE select Edit → Copy for Forum. The copied text (including the 3 back-ticks at the top and bottom) can then be pasted into your post.
As regards the actual problem, check as grb suggested. If you open a terminal to the serial port other than Serial Monitor, then make sure you close that first to release the serial port before trying to upload.
exit status 1 is not the error message. Find the real error. But first read the pinned post re ‘How to get the most from the forum’.
