During the 2^nd and 3^rd term, the students of 4^th of ESO have carried out some activities related to electronics. In task 1 the students learned what logic gates are and they looked for possible applications for them. In task 2, the students coded some LEDs with Arduino so that, the LEDs could shine to the rhythm of a song. Students showed the result of the task in Flipgrid, a video discussion platform, from where it was accessible to the rest of the classmates, who gave them feedback. The final project made with the LEDs and the oral expression have been evaluated with a rubric.
