Tinkercad — Learn IoT at Home?

With face-to-face classes disrupted during the pandemic in Hong Kong, Tinkercad provides an online tool that lets us conduct IoT experiments from home.

Tinkercad Experiments

Micro Servo Motor Control: Learn to connect and program a Micro Servo Motor, understanding position control principles.
Temperature Sensor Application: Combine a TMP36 sensor for automated control (e.g. rotating the motor when temperature exceeds a threshold).

Tinkercad simulates Arduino operations and is an excellent beginner's tool for IoT.
