I just finished my first year in college and took mostly programming classes, so when it comes to electronics, I am completely lost. I'm going to use an Arduino Uno for this plastic RC car that has 5 AA battery slots. If I wanted let's say ~12V instead of 7.5V, what are my options? I have a battery pack that holds 6 AAA. I thought of connecting them in series, but I somewhat understand why that isn't a great idea. In addition to my options, I want to know when it is okay to hook up batteries in series/parallel. For example, would it be okay to hook up one more battery in a series?
Thanks in advance!
