It was an online session, which began with Eng. Ahmed Wael discussing the crystal oscillator and how to configure it on simulation as it directly affects the delay and other related things. The session mainly focused on practicing DIO, and the attendees worked on several projects, including Ping pong with LEDs, Snake with LEDs, Pushbuttons, and the issues of debouncing.

After that, Eng. Eslam Helal discussed seven segments and their types and displaying numbers forward and backward on them. The presenters shared their screen to ensure that attendees were practicing and to help them if there were any errors.

Towards the end, Eng. Ahmed illustrated the task for the attendees, which was mainly a bomb made with 7-segments, LEDs, buttons, and a buzzer.
