Editing Tasks WiSe2021 (section)

=== Tasks and Submission (Deadline 13th of Jan) === 
* Task 1: Play a sound, PWM
** Connect the piezo speaker to an output pin
** Modify the example given in [[Piezo Speaker]] to play a part of a Xmas song

* Task 2: Read the distance with HC-SR04
** Connect the [[Ultrasonic Sensor HC-SR04]]
** Understand how to include a library in mycropython (see [[Tutorial Network]], [[Tutorial Display]])
** use the hcsr04.py library and read out the distance
** write the distance to the serial line

* Task 3: Implement Theremin-like instrument
** Connect the piezo speaker to an output pin (task 1)
** Connect the [[Ultrasonic Sensor HC-SR04]] (task 2)
** Change the tone (frequency) that is played based on the distance
** write the frequency you play to the serial line

* Task 4: Stepper Motor 
** Connect the stepper motor [[Stepper Motor and ULN2003]]
** Connect a button (see session 1)
** For a short press on the button move 45° and for a long press move 180° 
** '''there may be a problem with power - see [[Stepper Motor and ULN2003]]''' - if this is the case just build up the setup and the program and document this

* Task 5: 
** Connect the servo motor, see [[Tutorial Digital IO]] and [[SG90 Servo]]
** Connect a potentiometer to A0 and read the analog value
** Set the position (angle) of the servo based on the analog value
** '''there may be a problem with power - see [[SG90 Servo]]''' - if this is the case just build up the setup and the program and document this

* Submission:
** Deadline: 13th of January 2021 latest 23:59 (Wednesday)
