Reviewed Task2 and added README's

---Session 1---

Task 1:

Learn how to open Atmel Studio.

Read the code, what do you think it does?

Learn how to upload code.

Task 2:

Set up a button with pullup. Use this to control the led.

Task 3:

Add aditional logic so that the button toggles the led.

Task 4: (OPTIONAL)

Add the OLED board.

Find out where the buttons and LEDs connect.

Do something fun with the additional leds and buttons.

/*

* Check out the ATtiny4809 datasheet to find the correct ports and pins 

 * Take a look at the Atmega4809 Curiosity Nano board and locate "SW0" and "LED0".

 * Right below each of them you can see which pin they are connected to. For example, if it said PD5, this would mean Port D and Pin 5.

 * This info can also be found in the ATmega4809 Curiosity Nano Hardware User Guide here: http://ww1.microchip.com/downloads/en/DeviceDoc/ATmega4809-Curiosity-Nano-HW-UG-DS50002804A.pdf to find the correct ports and pins

	 * We want to send signals to the LEDs, in order to turn it off and on.

	 * We also want to be able to read the switches.

	 * This is done by setting bits in the PORTx.DIR register (in this case PORTD.DIR and PORTC.DIR)

	 * This is done by setting bits in the PORTx.DIR register (in this case PORTF.DIR)

	 * PORTx.DIR: 1 is output, 0 is input

	 * LED: 1 LED is off, 0 LED is on

	 * Button: 1 Button is open, 0 button is pressed

	/**

	 * In order to read from the switches, we need to give it a ground reference, via a pull-up resistor.

	 * If we don't, the switch will have a floating ground, and hence its value will be undefined.

	 * On the ATtiny4809, we enable pull-up by setting the "PORT_PULLUPEN" flag in "PORTx.PINnCTRL" high.

	 * On the ATmega4809, we enable pull-up by setting the "PORT_PULLUPEN" flag in "PORTx.PINnCTRL" high.

	 * See datasheet section 15 (I/O-ports).

---Session 2---

Task 1: Timer

Get hands on with timers and interupts to toggle a led at exact times.

Task 2: PWM

Continuing with timers, use them for pulse width modulation of LEDs

Task 3: UART

Write a UART driver to communicate with the PC. 

Preferably interrupt based.

 No newline at end of file

---Session 3---

Task 1:

Use the ADC to read the value of the light sensor on I/O 1 and send it over uart.

Task 2:

Write an SPI driver and and test it with the OLED screen and provided image.

Task 3: (OPTIONAL)

Use the screen and buttons to make a game! (Suggestion: Simon says)
