a 7 rgb LED chain used as a simple display device
a linear potentiometer simulating sensors which deliver analogue signals. A 12 bit analogue to digital converter (ADC) as well as a 8bit a digital to analogue converter (DAC) are available on the CPU card.

The cost of a complete set as described above is ~ 13 US $, shipping and VAT included. You can easily use the devices for 5 years, which will bring down the price per student and year to 3 US $. Of course. For a full school or university course you would add real sensors (e.g. temperature and humidity sensor, atmospheric pressure sensor, ultrasonic distance sensor, movement sensors ...) as well as real actuators like relays, motors ... which may bring up the cost to ~ 50 US $. Distributed over 5 years, this comes down to 10 US $ per student and year, which is still very reasonable.

The problem: How do we use such a system?

... and this is what these pages are all about.

The course or let's call it workshop consists of some minimal lectures and a maximum number of hands-on exercises. You will get exercise sheets and the solutions will also be available proving that the exercise can actually be done.
