Semesterplan and Tasks

  • Regular Online Session on Thursday 18:00-19:00
  • Tutors available in discord:
    • 10.12.2020 (Thursday) from 17:00-21:00
    • 16.12.2020 (Wednesday) from 17:00-21:00
    • on request - please let us know when you want to work on it

Session 1: Introduction (Monday 07th Dec)

  • Introduction to the course, presentation of the hardware.
  • Organisation - make teams of 2 people

Videos and Tutorials to watch

Tasks and Submission (Deadline 16th of Dec)

  • Unpacking of the hardware
  • Install the software on your computer, put the software image onto the ESP8266 D1 mini, see Tutorial Basics
  • Task 1: Digital IO
    • Connect 3 external LEDs and let it blink in different speeds
    • Connect a button to a digital input, when the button is pressed all LEDs should be on
  • Task 2: Analog In, PWM Out
    • Connect 1 external LED
    • Connect a potentiometer to A0 and read the analog value
    • change the brightness of the LED with the analog value (PWM)
    • write the analog value to the serial line
  • Submission:
    • Deadline: 16th of December 2020 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 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

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 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
