Electronics and Digital Computing: The concept of a Boolean variable is explained and its representation with switches or merely in terms of voltage levels is discussed. An introduction is made to how Boolean variables can be used as binary digits in the base-2 number system. A standard integrated 4-bit digital adder circuit is mounted on a protoboard and the sums are verified.

Introductory Arduino with IoT: The workshop provides an introduction to the basic functions of Arduino and a look at the IoT (Internet of Things) possibilities offered by circuit boards. Electronic circuits are also be worked on with breadboards. No prior knowledge of Arduino or programming is required.

Basic cryptography: Activities are carried out to illustrate cryptographic methods that have been used from the origins of cryptography (Caesar's method) up to the 20th century (Enigma machine).

IoT with Arduino: The workshop explores the Wi-Fi capabilities of an ESP8266 board. Participants connect the board to the internet and control it from a web page. They develop a game in which, by solving the small interconnected tests they have designed, a victory message is displayed on the projector. The workshop requires prior contact with Arduino or a programming language and basic notions of electronic circuits.
