** 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

* Task 4: Ideation (for the group projects). Generate ideas within your team using the following process:
**First, before meeting your partner, everyone of you should independently think about 5-10 issues with remote connectedness (eating, dancing, etc.)
**Second, before meeting your partner, everyone of you should think independently about 5-10 hardware components (sensors, actuators, etc.)
**Third, together (!) randomly pick one issue and one hardware component and imagine a project. Save your solution! Create and describe at least five projects this way. So, person A picks both and describes a solution. Next, person B does the same, and so on.
