Tutorial : Ultrasonic Distance Sensor for S5D9 IOT.

Hi all,

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.   


Have fun,
