This study evaluates an Arduino-based kit designed to teach the detection of exoplanet transits through signal processing. The kit replicates the entire process: acquisition via a photodiode of an LED ‘star’ occulted by a motorised ‘planet’, followed by FFT analysis using tools identical to those used, for example, in the diagnosis of electrical machinery. Conducted with pupils at a youth centre in Oran, Algeria, this two-hour workshop was evaluated using pre- and post-training tests. The results show that the majority of pupils correctly identified the orbital period from noisy data following the activity. All resources are open source. This work supports the IAU-OAE 2026 objective of ensuring reliable access to science.

About Kheireddine DEHAR

I am a PhD student at the Mohamed Boudiaf University of Science and Technology, Oran (USTO-MB), where I am working on my thesis on the diagnosis of electric drives through the analysis of vibration signals, and I am a part-time lecturer on the Acoustics module at USTO-MB.
I am currently president of the ‘El-Qamar Astronomical Observatory’ Association in Oran, an organisation dedicated to promoting astronomy and scientific culture in Oran, and an active member of the ‘El-Battani’ Astronomy Association in Oran, a pioneer in this field in Algeria.
I am a member of the UAE-OAE team responsible for the national coordination of astronomy education in Algeria (NAEC-ALGERIA).
