Struggling with Pinky Finger – Any Exercises or Tips?

I recently got my first electric guitar and started trying out some basic riffs. My pinky finger feels really weak and clumsy. Every time I try to hit notes with it, I either miss or get a muted sound.

It’s frustrating, especially when I try to play fast or stretch across frets, my pinky just can’t keep up.

What exercises can help building strength and control in your pinky?
