The first is Timer 0, an 8-bit timer capable of phase-correct and fast PWM used for functions such ... OUTPUT); } void loop() { analogWrite(PWM_pin, level); delay(1000); analogWrite(PWM_pin, 0); delay ...

You will need the Arduino Board, a 560Ω resistor, and LED and the code example below. We set the pinButton variable ... we set the pin 8 as INPUT and pin 2 as OUTPUT. In the loop() function we read ...

The Arduino Mega's PWM pins are digital ... the input value into four as seen in this basic example code or by using the map() function, as you can see in this Analog In, Out Serial sample sketch.

[Electronoob] has a good tutorial about how to pull this off with an Arduino. You can also see a video, below. The demo uses a 3D printer hot end, a thermocouple, a MAX6675 that reads the ...
