Expert Solution

Step 1: Introduction

To write a program in assembly language for the ATmega328 microcontroller that sets PORTB.2 when a button is pressed or a switch is turned on, and after 3 seconds, PORTB.3 is turned on using Timer1, you can follow these steps:

Initialize Timer1 to generate a delay of 3 seconds.
Configure the pins for the button and PORTB.2 and PORTB.3 as input and output, respectively.
Continuously check the status of the button.
When the button is pressed (or the switch is turned on), set PORTB.2.
Wait for the Timer1 to finish counting (3 seconds).
After 3 seconds, set PORTB.3.

Here's an assembly program for the ATmega328 microcontroller that sets PORTB.2 when a button is pressed or a switch is turned on, and after 3 seconds, PORTB.3 is turned on using Timer1. This code assumes that the button or switch is connected to Pin PC0 and that the ATmega328 is running at a clock frequency of 16 MHz.
