5.- Design a microcontroller system to control a sprinkler controller that performs the following tasks. We assume that your microcontroller is clocked at 10 MHz and has a 16-bit free-running counter. The sprinkler controller system controls two different zones by turning the sprinklers within each zone on and off. To turn on the sprinklers in a zone, the controller needs to receive a 152.589 Hz PWM signal from its microcontroller. To turn off the sprinklers in the same zone, the controller needs to receive the PWM signal with a different duty cycle. A.-Your microcontroller needs to provide the PWM signal with a 10% duty cycle for 10ms to turn on the sprinklers in zone one

Operational Amplifier

An operational amplifier also called op amp is an integrated circuit or analog circuit that takes input as a differential voltage and produces output as a single-ended voltage. It is an IC that can amplify weak electric signals.An op amp has one output pin and two input pins. The basic role of an opamp is to amplify the voltage difference between the two input voltages. It is also used in filtering or to perform mathematical operations or in signal conditioning.
