Study guide
In this lab you set up Arduino and Raspberry Pi, interface LEDs and buzzers, push buttons, IR and LDR sensors, DHT11 temperature and humidity sensors, relays and motors, OLED displays and Bluetooth, upload and retrieve data from ThingSpeak, install MySQL on a Raspberry Pi and publish data to an MQTT broker. Check wiring and power before connecting components.
Why IoT and Its Applications Laboratory Matters
Working IoT projects are tangible portfolio items and show end-to-end skill from sensor to cloud.
How to Prepare for IoT and Its Applications Laboratory
- Double-check wiring and voltage levels.
- Log sensor data and graph it.
- Document circuits with diagrams and photographs.
