>1. The motor demo didn't work for me (Firefox on Android). Nice to say it was made by Claude.

oh! i did tested on firefox with different devices on my laptop. but not in actual android phone. thanks for flagging it

>2. Voltage isn't like gravity. It's literally called potential. Voltage is the water being high up on the mountain. Gravity is the gravity, which was kinda the point of the analogy, no?

yeah! my bad. i might have wrote few things when i was just reading up and writing as i am trying to internalize what all these things mean

>5. PWM wasn't explained right here. You can most certainly vary the voltage without PWM, and it's not just any old modulation you want. You want a binary output so your transistors don't go linear, and you can control the average power. PWM is easy for linear scaling. But you could presumably use other modulations.

there are probably 10 more ways to make voltage dance - and i only read about two. one is resistors and other is PWM.

>Would be good to understand what the power chain is to make sure nothing blows up.

The blog has link which points to exact wiring instructions including adding buck converter. again! the purpose of this blog is not to explain every bit in detail. it's about what i have learned - because before doing all of this - i had zero clue about everything

yeah! voltage is not gravity. i might have wrote that in my flow.
