Student access to laboratory experiments is critical in undergraduate engineering courses since it integrates theory and practice. The access of students to such practical examples helps them to understand and apply what is learned. However, due to rapid technological advancement, educational kits can quickly become obsolete. Besides, there are many known commercial platforms for training.Many of them have steep prices, which makes their availability dicult for every student. The present work proposes a low-cost ATMEGA-based system as the main device for an educational tool for training Control System Theory. The system enables the students to test dierent control strategies through the use of a simple educational kit.
