So long story short, I’m pretty new to electronics (so please excuse if some of my terminology isn’t correct) and was trying to wire a high torque servo for my school project and ended up frying my computer and breaking it, so now I’m a little worried to try again. Basically, how I wired it was I had my positive and negative servo pins connected to my breadboard (directly to the positive and negative pins on my breadboard), my orange servo wire connect to pin 9 on my arduino, ground on my arduino connected to the negative side of my breadboard, and I had the positive and negative sides of my batteries connected to the negative and positive sides of my breadboard. I had two 3.7v, 2200mAh Flat Top batteries and I know now that this was not the correct way at all to wire this since my computer broke the second I plugged my arduino into it lol. So I guess my question is. What is the correct way to wire this servo and can I use normal batteries or do I need a power supply? I’m adding pictures of how I wired it, but ignore the accelerometer and random loose wires those are for different aspects of my project lol. Batteries I have available: the ones I mentioned, double a’s, 9v, 12v, a cheap $5 portable charger from target that is 5v
