==Session 2: Sensors and Actuators (Thursday 17th Dec) == 
* Discussion of sensors, actuators, libraries
* Organisation - check that teams of 2 people exist

=== Videos and Tutorials to watch === 
* Understand how to connect a servo and how to move it, see [[Tutorial Digital IO]]
* learn at how to create sounds, see [[Piezo Speaker]]
* look at how control a stepper motor [[Stepper Motor and ULN2003]]
* get familiar with how to connect the [[Ultrasonic Sensor HC-SR04]]

=== 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)
** For each task submit a video of max 30 seconds (should show the setup, your code on the screen, an the system functioning)

==Session 3: Networked IoT Systems (Thursday 14th Jan) == 
* Network library, Display, ES32, MPU6050

=== Videos and Tutorials to watch === 
* Understand the network library [[Tutorial Network]]
* Understand the display library [[Tutorial Display]] (requires coming to the lab for soldering/picking up ESP32)
* Understand the [[MPU 6050]] Sensor and I2C connection (requires coming to the lab for soldering)

=== Tasks and Submission (Deadline 20th of Jan) === 
* Task 1: Play a sound over the network, connected devices
** Connect a potentiometer to A0 and read the analog value
** Write the value to the network [[Tutorial Network]]
** Read the value from the network from your team colleague
** Play a sound based on the value you get from the network

* NOT POSSIBLE as we have no access to the lan: Task 2: Subtle communication, connected devices 
** (requires coming to the lab for soldering)
** Solder the Pins onto the MPU 6050
** Connect the [[MPU 6050]] Sensor as I2C device 
** When the sensor is moved, write a value to the network [[Tutorial Network]]
** When the device has not been moved for 10 seconds, write a different value to the network
** Read the movement value from the network from your team colleague
** Switch on the LED if the remote device has been moved

* Alternativ Task 2: Subtle communication, connected devices 
** Connect a Sensor ([[LDR]], [[Ultrasonic_Sensor_HC-SR04]], [[PIR_Sensor]], ...)
** If the sensor value changes, write a value to the network [[Tutorial Network]] (not more than every 5 seconds)
** Read the sensor value from the network from your team colleague
** Switch on the LED if the remote site is active (changing sensor values)

* Task 3: Quotes on the Display
** (requires coming to the lab for soldering/picking up ESP32)
** put the micropython image onto the ESP32, see [[Tutorial Basics]] and session 1
** Show every minute a random quote on the display (at least 3 different quotes) [[Tutorial Display]]
