Hello!

We are happy to announce our first workshop of the new academic year! This
time we will teach you how to use the *Bonsai* reactive programming
language.

Many experiments require us to synchronize multiple data streams— from
cameras, sensors, microscopes—precisely deliver stimuli, and, quite often,
do everything in a *closed-loop* setting. The fact that different devices
use different software doesn’t make this task easier.

One of the best—and open—solutions to these challenges is *Bonsai*, a
reactive programming language that allows you to collect data from multiple
systems, from calcium imaging through sound recordings to sensors, and to
control output devices—such as feeders, motors, or stimulus delivery
systems—to build *closed-loop* paradigms. It is easy to learn, implement,
and is robust.

During our workshop, we will introduce the basic logic of Bonsai; cover
loading and saving data; working with a camera to track animals; and the
basics of closed-loop experiments. We will also cover using Arduino
alongside Bonsai to control experimental equipment and to save data from
your sensors.

*Requirements:* A Windows computer and a webcam.

The workshop will take place on *Oct 17, 9:45 AM–5:00 PM* at *COS,
Heidelberg Institute*. Please find more info and the registration form here:
