About this course
An Arduino-linked IoT course for makers who want to use simple boards in connected systems. Students build sensor nodes, format telemetry, communicate over serial, and bridge readings into an ESP32 or Raspberry Pi gateway.
What you will be able to build
- 01Build Arduino sensor nodes
- 02Format reliable telemetry messages
- 03Use serial communication for device gateways
- 04Separate node logic from gateway logic
- 05Create simple actuator control protocols
- 06Debug data flow across boards
