Arduino.
Arduino shows up where Remiam needs a small, dedicated microcontroller bridging the digital and physical — Virtual Santa's interactive Christmas-tree lights (kids picked the colour live, an Arduino pinged a custom API), an alternative socket-server variant for the Cipher Room escape rooms, prototype sensors for client builds. The studio writes Arduino sketches in C++ via the Arduino IDE and stores firmware in git alongside the higher-level Nuxt apps that talk to it.
Virtual Santa
A Covid-era WebRTC platform letting parents book video calls with Santa. Kids picked Christmas-tree lights live, driven by an Arduino pinging a custom API at the booked time.
Cipher Room
A series of physical digital escape rooms built for a UK public-sector security body — four iPads facing each other around a central lockbox, all synced through a Raspberry Pi socket server that also drives the lockbox's lock and unlock as part of the puzzle. 1–4 players, multiple full-length and mini versions, designed to teach security practices through play.
