In this video, we look at the difference between digital signals and analogue signals. You'll get to learn how to control and LED with analogue signals on an Arduino board.
On your remark about the bright values being hard to distinguish: it's a well-known feature of human senses, and this is what gamma-correction solves. You could use a gamma function to map percentages (0..100) to the PWM levels (0..255) in a way that looks more linear to the eye. But the ratio of 2.55 (255 / 100) doesn't leave much room for spacing out the values enough. Would be better if the PWM had at least 9 bits of resolution (512 levels), or we could use the input range of 1..50 instead of 1.100 (with 50 meaning full brightness).
Great video, I like your style of talking and explaining. I'm familiar with the topic, and enjoyed your explanations anyway!
Thank you for watching Violet and for the great feedback. Arduino is quite an interesting concept and pretty awesome.

Thank you so much Vilolet for sharing this 👏
