Controlling and regulating equipment by means of microcontrollers has become indispensable. Our students will frequently have to deal with installations with one or more microcontrollers in their later work environment.

Brief description

In this series of lessons and labs, students get acquainted with the programming of microcontrollers. In this way, we form the link between application development (programming) and the control of equipment (electrical engineering). The knowledge and experience from this series serve as foreknowledge for a professional orientation, or as a basis for a further study choice.

Students learn to build simple circuits and connect these to the microprocessor. Students are introduced to programming skills and programming a simple application with the Arduino. After this series, participants can design and build their own first programmable prototype.

Target group

The series of lessons and labs are designed as a block of approximately 3 months for MBO students. By varying the depth during the performance, the series is suitable for a wide audience.

Foreknowledge

No prior knowledge required.

Continuation

The skills acquired are then applied in a specific application, in the following block:

Lab test

The lab test consists of a recurring pitch moment, per person. In each lab, you may be asked to explain what you are doing. Imagine that this is your manager’s manager, who comes to see what’s going on on the shop floor. Your pitch is short, clear and testifies to knowledge and insight.

You make sure it’s your turn. So this is not all possible in the last minutes of the lab. The first round is an exercise and does not count.

  • The technique, correct and sufficient content
  • Briefly, it fits in 30-90 seconds (succinctly) or you need 5 minutes (not succinctly)
  • Completeness tells your story what we see in your Lab
  • Passion, you can convey to the listener why your solution is a good one. Or let them know that you’re working through the night. Or surprise us with extras.
  • Lab result, you’ve been able to build what was intended…

You score a maximum of 5 times 2 points, and your grade is an addition.

Lab log

You write your personal lablog in a way that we (public or not) can access it. You can use it to describe the results of your weekly labs, on average half an A4 page per lab including photos. You can also describe your final project, which you write as a transfer document to a colleague who will continue your work with the same training.

Here you score points on the same criteria: Technique, Compactness, Completeness, Passion and Result.

Lesson program

Each block has 10 weeks, one of which is reserved as a buffer week.

Week 1. Introduction and first lab

  • Theory. The goal is to give an interesting approach to the teaching of hardware and IOT. Our approach is focused on the LABs, and meanwhile, we are growing in employee skills.
  • Self-regulation and collaboration. https://junioriot.nl/zelfregulatie-en-samenwerken/
  • Theory NetAcad: 0. Welcome to IoT Fundamentals: Connecting Things
    Overview: this training teaches you on circuits and software. Labs: digital, on physical equipment, packet tracer (network simulation tool). Quiz and exams for the course are available in the Cisco Networking Academy.
  • Teaching materials NetAcad: 1. Things and Connections.
  • LAB – Build a vibration robot – https://junioriot.nl/soldeeroefening/
    Each participant builds an item that can be taken home.
    we explain how to handle the soldering iron neatly and safely
    we explain that you should never solder on a battery, and why (S&T)
    You test the battery with an LED and examine which battery holder legs you use to turn the LED on.
    You build your own vibrating robot with battery, battery holder, vibrator – and add a switch if necessary.
