AVR - Programming hardwareregisters for an Arduinoboard

This repository contains five different branches, each focusing on specific tasks related to programming AVR hardware registers for Arduinoboards.

Branches and Tasks

1. Deluppgift01-Timer1 (Timer)

Instructions:

• Configure TIMER1 to blink an LED with 200 ms on/off cycles.
• Use GPIO code to control an LED connected to Arduino/Freenove pin 3.
• Utilize timer compare A interrupt to toggle the LED.

2. Deluppgift02-ADCread (ADC from Potentiometer)

Instructions:

• Connect a potentiometer as a voltage divider to pin A0.
• Set up ADC and read the value via hardware registers.
• Print the read value and calculated voltage on pin A0 every second via the serial port.

3. Deluppgift03-LEDcmd (LED Control from Command Line)

Instructions:

• Connect an LED to pin 3 (PWM capable).
• Implement a configurable timer with Timer1.
• Create a command interpreter that handles the command ledpower <power> <time>.

4. Deluppgift04-ButtonCounter (Using Counter Mode with Timer1)

Instructions:

• Write a counter for the number of button presses.
• Use Timer1 to measure the input from pin 5.
• Print the number of button presses every second.

5. Deluppgift05-RampLED (Control PWM up and down)

Instructions:

• Ramp an LED's power linearly from 0-255 and then down periodically.
• Control the ramp time via a command sent through the serial port, e.g., ledramptime 500 milliseconds.
