Version vom 28. April 2022, 14:28 Uhr

Ankündigung: https://www.kobakant.at/DIY/?p=9589 TH 28.4.2022, 11-14:00 (3h) + FR 29.4.2022, 10-15:00 (4h)

This 2-day workshop aims to give an overview of a selection of wireless communication technologies good for sending sensor data between small devices and computers, and provides concrete examples for a subset of the selection. For example how to send data from an Arduino with WiFi or Bluetooth capability to a computer or how to send data between two such Arduinos or also between computers. We will work with protocols such as TCP, OSC, MIDI and MQTT.
