More than 1,000 children aged between seven and 17 are showcasing their computer coding, hardware and robotics projects at an exhibition in the RDS in Dublin today.

The annual Coderdojo Coolest Projects exhibition, which is open to the public, will see more than 700 individual and group projects on display.

The young people are coming from all over Ireland, as well as from other countries, including locations as far afield as Argentina and Japan.

Among the projects this year is a face-recognition security system for older people and an adventure game to teach farm safety.

There is also an experiment to determine if the working environment in space is comfortable to live in and a health tech app that helps people with special needs to communicate easily with family and friends.

It is the seventh year of the event, which is organised by the Coderdojo Foundation.

Throughout the year, the young people develop technology projects at their local Coderdojo or similar club using coding languages such as Scratch, Python, HTML and Javascript, as well as hardware such as Raspberry Pi, Arduino and other robotics kits.

Co-creator of Raspberry Pi Pete Lomas is the keynote speaker at this year's Coolest Projects.

Last year, Coderdojo Foundation announced a merger with Raspberry Pi Foundation.

There is also a range of hands-on activities for all ages at this year's event, including a STEM escape rooms, flying drones, VR headset testing, creating wearable technology pieces and a giant circuit board puzzle as well as demonstrations, workshops and panel discussions.

The event is taking place in the RDS Simmonscourt and is open to the public until 5.30pm.
