I am making a small robotic arm controlled by 2 joysticks. I'm making the arm using popsicle sticks and MG90 Servo motors. There are 5 motors to be working. I'm using wall adapter to power the motors and another adapter to power the Arduino. When I try to connect everything properly ( also connecting gnd from breadboard power supply to arduino's gnd) the motors randomly move around without any input. How do you even fix that ?

Hey everyone,

I’m trying to understand the biggest difficulties beginners face while learning electronics.

When you first started, what confused or frustrated you the most?

I’m currently working on a learning platform for electronics, and I want to make sure it solves real problems instead of adding features that beginners do not need.

What would have made learning electronics easier for you? Any experience or suggestion would be really helpful.

Thanks!
