    Right now I am trying to create a schematic including the following components:

    ATtiny44A-PU microcontroller
    LM35DZ Temperature Sensor Analog Serial
    RF link transmitter WRL-10534
    PIR motion sensor SEN-08630

    I am having a hard time trying to figure out what the different pins are for on the microcontroller. Is anyone able to help me out? I have attached the data sheets for the components.

    Microcontrollers are general purpose programmable devices. You can use any pin for almost any function you desire. Microcontrollers have dedicated features and hardware and will use specific pins.

    If you are now learning to use a microcontroller for the first time, in fact, even a seasoned user attempting to use a new microcontroller for the very first time, forget about trying to do anything fancy for starters.

    The first thing you should attempt to do is make the microcontroller turn an LED on and off repeatedly.

    That's your first assignment.

    I have used several before. However, I have never used this particular kind before, and I wasn't sure if it mattered what I wired each pin to or not. I just wanted to check and make sure I was doing it properly.

    Each pin, except VCC and GND can be used as GPIO (general purpose input/output) or for specific alternative function as indicated in braces.

    Check the datasheet for pin functions and how to activate the desired function:
