I need help writing an experience summary for a job

 I'm asked to provide the following:

"Would you mind sending me a brief description of what your experience was within your internships? If you could do it in a resume format, where you would put your experience, would be great. You can absolutely do bullet points! I want to make sure to accurately depict all of your knowledge and experience in addition to school when I present your resume to the Hiring Manager."

In the internship I've used a micro controller called Arduino. 

please keep it basic, simple, and brief as I haven't work with this device much, although I'd like to project that I have a bit of knowledge about the device. 

More information are provided in the file I've attached.
