Barcelona School of Telecommunications Engineering

Workshops 'STEM&You'

STEM&TU programme students working in a laboratory at ETSETB

The Universitat Politècnica de Catalunya (UPC), together with the Government of Catalonia, takes part in programmes to promote STEAM (Science, Technology, Engineering, Arts and Mathematics) among secondary school and upper secondary school students. In this context, the ’Barcelona School of Telecommunications Engineering (ETSETB) at the UPC presents a new edition of the STEM&Tu project.

Through the STEM&Tu project, we offer workshops designed to bring students closer to science and technology from the perspective of Information and Communication Technologies (ICT) and telecommunications. The activity takes place in a single session. After an initial presentation about STEAM and the university, the workshops are held. They are delivered by a student from the School of Telecommunications Engineering, who will also share their own experiences of university life.

Things to bear in mind:

  • There are basic and advanced workshops. The basic workshops are suitable for secondary and upper secondary school students, while the advanced workshops are only for upper secondary school students. All workshops have a maximum capacity of 20 students.
  • They last 2 hours. A guided tour of the main facilities at the UPC’s North Campus can also be included (allow an extra 30 minutes).
  • They will take place from 21 January to 10 February 2027

STEM&Tu basic workshops 2027

  • Electronics and digital computing: The concept of a Boolean variable is explained, including how it can be represented by switches or simply by voltage levels. Students are introduced to the use of Boolean variables as binary digits in the base-2 number system. They then build a standard integrated 4-bit digital adder circuit on a breadboard and check the sums.

  • Catch the wave: A workshop exploring the properties of electromagnetic waves. Through engaging, interactive activities, students explore concepts such as frequency, wavelength, propagation speed, refraction and wave polarisation. Everyday examples and situations are used to encourage curiosity and practical understanding.

  • Basic cryptography: Activities will illustrate cryptographic methods, from their origins (the Caesar cipher) to the 20th century (the Enigma machine).

STEM&Tu advanced workshops 2027

  • Electronics and analogue computing: Students learn how analogue electronic circuits can emulate mathematical systems or linear physical models, such as addition, subtraction, integration and differentiation. They see how an analogue circuit can be used to represent a linear equation of the form y = ax + b.

  • Who can throw the lunchbox the highest?: By throwing an object towards the ground, students determine the height reached, how long it stays in the air and its speed when thrown and when it reaches the ground. Using technology such as Arduino, accelerometers and GPS, they explore concepts including acceleration, speed, distance, time, gravity and satellite navigation (GPS, GNSS).

  • Talk to the rubbish bin: Students build a system using artificial intelligence to recognise simple voice commands, such as “open” or “close”, to control the lid of a rubbish bin. The workshop covers concepts such as the Internet of Things (IoT) and artificial intelligence.


Registration will open soon.
