---++ Exercise 1:

Connect to your ESP32 with minicom or thonny.

Using REPL:
   * <p>print “Hello World!”</p>
   * <p>read in a text using <i>input() </i>and print it</p>
   * <p>Calculate</p> <p><img align="middle" alt="calculations.png" height="52" src="%PUBURL%/UCC_Course_2020/Exercises/calculations.png" title="calculations.png" width="142" /></p>
   * <p>Calculate sin(30°) <br /> If you see errors, how do you correct them? Are the results correct?</p>
---++ Exercise 2:

Write a script that assigns the values 5 and 3 to the variables a and b respectively

Print the results of 4 basic arithmetic operations:
   * <p>a+b</p>
   * <p>a-b</p>
   * <p>a*b</p>
   * <p>a/b</p>
Which result do you observe for division? Can you correct?

Improve this program asking the user to enter 2 integers separated by a space. If this happens when the user mistypes and enters something that is not an integer can you capture the error and simply ask him to repeat his input until you get 2 correct integer numbers?

Bonus points: Writing a parser is quite easy if the numbers are separated. It is quite a bit more tricky if you allow entering calculations with spaces between the operands and the operator. Can you write a parser accomplishing this?

---++ Exercise 3:

Ask the user for 2 integer numbers. Check with one is bigger and print the result:

Running the program should result in output as shown below:
