Here is the link to the demo tonight at IOT community meeting.
Learn to connect the 5V popular distance sensor to the 3.3V S5D9 IOT board.
Use one shot timer to generate the trigger pulse to start sensing.
Use timer and input interrupt to measure the return echo pulse from the sensor.
It is an intermediate tutorial.
Michael, thanks for building this tutorial. I ordered these Elegoo HC-SR04 Ultrasonic Distance Sensors to go through your tutorial with the board from the AE-CLOUD1 kit (same board that is in the S5D9 IoT Fast Prototyping Kit)
