Generally Pulse Width Modulation is prominently used in controlling & communication applications. Here, we are using this technique to changing the light intensity of led.
This block controls MicroDAQ PWM modules. One of three PWM modules can be selected (PWM1, PWM2, PWM3), PWM period is defined with 1us resolution, ‘Polarity’ parameters allow to generate inverted PWM waveform. Blocks input parameter range is 0-100 (duty in %).
