Steve Zafeiriou (b. 1998, Thessaloniki, GR) is a New Media Artist, Technologist, and Founder of Saphire Labs. His practice investigates how technology can influence, shape, and occasionally distort the ways individuals perceive the external world. By employing generative algorithms, electronic circuits, and interactive installations, he examines human behavior in relation to the illusory qualities of perceived reality, inviting observers to reconsider their assumptions and interpretations.

Who is this for?

Whether you’re an electronics enthusiast, an IoT engineer, or an artist building interactive installations, this hub is designed to teach you how to think in microcontrollers. If you want to understand how Arduino, ESP32, and sensors can move from hobby projects to robust systems; on stage, in galleries, in products or prototypes, these resources are for you.

  1. Microcontroller Basics: Understand architecture, GPIO, memory, timers, and power considerations so you can choose the right board for each project.
  2. Sensor Integration: Interface reliably with motion, distance, GPS, biometric, and environmental sensors, and interpret the data they produce.
  3. Communication Protocols: Work confidently with UART, I2C, SPI, and wireless connectivity (Wi-Fi, Bluetooth, LoRa) to link devices and software such as TouchDesigner.
  4. Hands-On Projects: Follow step by step builds that move from blinking LEDs to full interactive systems used in installations and prototypes.
  5. Industry & Creative Trends: Stay informed on new boards, tools, and workflows for embedded systems, creative coding, and physical computing.
