The three basic parameters of PWM:
1. Die amplitude of the pulse width (minimum/maximum)
2. Pulsefrequency
3. Voltage level
The Mega2560 has 6 interfaces, supporng PWM: digital PIN 3, 5, 6, 9, 10 and 11.
In a previous project, we used a digital signal to control a
LED.
Now we are going to use a potenometer to adjust the
brightness of the LED.
