PWM is available on PORT that has Timer. In Uno, it is pins 3, 5, 6, 9, 10, 11. But, we can also turn any pins to PWM. We can emulate the PWM signal by turning ON (HIGH) & OFF (LOW) real quick. In this activity, I used Software PWM to control the brightness of the LED.
The PWM is 10%, so the LED is dimmed
Most of the time, we used Servo library to interact with Servo. We just supply the angle and the Servo moves to the position. But, what 'message' exactly did Arduino send to the Servo so that it moved?
Turns out, the servo can be controlled via a PWM signal.

not really sure how does he goes 360 there 🤷
