Arduino + Visual Basic : PWM Control

Vb Pwm Banner

Pulse Width Modulation or PWM allows the microcontroller to mimic analog control by turning the voltage on and off very quickly. The Arduino has an 8 bit PWM built-in, which means it has up to 256 levels of control. ( 2^8 = 256 ). These 256 levels of control actually determines the percentage of the ON duty cycle over the …
