I'm an educator and am using Arduino with my 5th grade classes though the education starter kit. They've been working on the "Sports Robot", "Windshield Wiper", and "Dimmer Switch" lessons but we cannot get the codes to function. They keep reading error messages. Does anyone have these codes we can simply cut and paste into the program? They're not learning the coding language in these lessons and I'm happy to provide them with the working code in order to get their projects functioning.
I am not having much luck finding documentation for a Arduino education starter kit and, frankly, don't know for sure which of the many many kits that you have.
It may be easier if you were to post the codes that you are trying to run and the errors that result. Then we can fix them.
Use the IDE autoformat tool (ctrl-t or Tools, Auto format) before posting code in a code block.
Please include the entire error message. If you use the Arduino IDE, it is easy to do. There is a button (lower right of the IDE window) called "copy error message". Copy the error and paste into a post in code tags. Paraphrasing the error message leaves out important information. If not using the IDE, copy and paste the entire error message.
Please post wiring diagrams or schematics that go with the codes so that we can know the hardware setup.
I suggest that you take this as an opportunity to teach the importance of asking a good question. Please read the how to get the most from the forum post. The post contains information on what we need to know in order to help you.
