Designed for our collaboration with Treatment Action Group for the 2018 AIDS Conference. Learn more.
This project uses sonar to detect when people walk through a doorway. The signal is sent to an arduino, which triggers lights (and possibly sounds) and counts the person on 8in LED numbers overhead.
The project uses:
Some of the wired connections were too delicate for use in the field.

We should do this as we go along. It starts now!
Experiment with designs, or creating specifications for building on site.
