What is the function of a timer in microcontroller applications?

  • To measure time intervals

  • To generate PWM signals

  • To synchronize multiple devices

To control memory access

Answer explanation

Explanation: Timers in microcontrollers are used to measure time intervals, generate precise delays, and trigger events at specific time intervals.

Which of the following ADC resolutions provides higher precision?

  • 8-bit

10-bit

  • 12-bit

16-bit

Answer explanation

The resolution of an ADC determines the number of possible digital values it can output. Higher resolutions, such as 16-bit, provide more precision and can represent a wider range of analog values with greater accuracy.

What is the role of the watchdog timer in battery-powered devices?

  • To conserve power by reducing clock frequency

  • To detect low battery voltage and trigger a shutdown

  • To synchronize multiple devices in low-power mode

  • To periodically wake up the microcontroller to check for system health

Answer explanation

Explanation: In battery-powered devices, the watchdog timer can be used to monitor the battery voltage. If the voltage drops below a certain threshold, the watchdog timer can trigger a shutdown to prevent damage to the device

In a PWM-based LED brightness control system, what parameter affects the LED brightness?

  • Duty cycle

  • Frequency

  • Voltage level

  • Current limit

Answer explanation

  • Explanation: In PWM-based LED brightness control, the duty cycle determines the proportion of time the LED remains on compared to off. Higher duty cycles result in brighter LED illumination.
