- 3. Describe a control system for an airconditioning System of a car, where the driver sets the desired temperature inside the car and compares it to the exterior temperature. The controller controls the temperature -ure sensing, unit providing constant temperature relative to the drivers setting.arrow_forward10. Consider you are interfacing a switch and two LEDS (L1 and L2) with LPC1769 MCU. • When the switch is ON (logic HIGH), LI is ON, and L2 is OFF. • When the switch is OFF (logic LOW), L1 is OFF, and L2 is ON. • Switch is interfaced with port 1- pin 2, L1 with port 1- pin 3, and L2 with port 1- pin 4. • Initially L1 is ON, and L2 is OFF.

- The input of an IC requires a constant 5 V, but the supply voltage is 9 V. Use thevoltage divider equations to create a voltage divider with an output of 5 V. Assumethe IC has such a high input resistance (10 MΩ) that it practically draws nocurrent from the divider.arrow_forwardDesign a 1-minute timer using a 60 Hz power line as an interrupting source. The output ports should display minutes and seconds in BCD. At the end of the minute, the output ports should continue displaying one minute and zero seconds.arrow_forwardA taco generator is use as a sensor to detect the speed of a rotating motor. The o/p of the tacho is between Ov and 5v where the midrange (2.5v) is equivalent to that the motor is standstill. When motor accelerates CW toward full speed, the tacho o/p will vary from 2.5v to 5v and when the input of tacho varies from 2.5v down to Ov means the motor is accelerating towards cCW. The Scenario is to reflect the equivalent speed on two SSDS which one will read the equivalent speed of reading 5 for maximum Cw (5v) and the other will also read 5 for maximum CCW (Ov) equivalent speed in the reverse direction.

The pulse width is between 1.0 to 2.0 ms, with 1.5 ms setting the servos to the center. • We need a resolution of no less than 1 us (micro second) for the pulse width change. • The timer used for the PWM generation has a 16-bit prescaler and a 16-bit counter. • The clock to the prescaler is 10 MHz. Determine the following (which may not be unique): 1. The range of PSC that satisfies the requirements for resolution and period of the pulses. 2. The value of PSC that can provide us with a PWM resolution, the multiple of which will be 1 us. 3. The PWM resolution for the above choice of PSC. 4. The value of ARR. for the above choice of PSC? 5.
